I'm working on a online tutorial on Python 2.7 and on exercice is to make a basic text
game. I'm very new to programming, and still working on the basics. I wish to make "move"-function I can call in all the "rooms" in the game, and deside the movement with args. The rooms in the game will be other functions i will call in the "move"-function.
In the example below i want to make it possible to choose for 4 directions using inputs n,e,s,w but only one will take the player to the next "room"-function called room_1 (not shown in the code here).
My problem is that it does not ask for input, but jumps straight to my room_1 function. It's not even printing the print "where do you wanna go? \n"
def move(north, dest_n, east, dest_e, south, dest_s, west, dest_w):
while True:
print "Where do you wanna go? \n"
movement = raw_input()
if movement in "n":
print north
dest_n
elif movement in "e":
print east
dest_e
elif movement in "s":
print south
dest_s
elif movement in "w":
print west
dest_w
else:
print "Not a valid direction. \n"
print "Use n, e, s, or w to move."
move(
"the door is locked!", '',
"You are not going that way.", '',
"Wall.. nope, not that way!", '',
"You move through the corridor", room_1()
)
Sorry if im being unclear about something, as I'm new to programming:)
Thanks!

(Using Sikuli IDE -288 20/04/19 on Windows 10)
I am currently having issues with a portion of code that runs correctly the first time around, but the second time where the function is looped instead of overwriting information created in the first iteration, it is somehow using the old information.
A function called selectRewards() is called, and it takes a few screenshots of the reward region over a few seconds to gather a useable still of an animation, the file name is numerically incremented. Then the function creates a Finder using the screenshots starting with screenshot 1. The Finder, and image I want to check against is passed into a search() function where it should be using the passed finder and image to find matches. It checks for all defined images in screenshot1, screenshot2 etc. until matches are found. And the matches are selected on the screen using coordinates from the screenshot image.
This all works well in the first iteration of the selectRewards(), it cycles through the screenshots and finds the images on a stable screenshot, but when the function is called again the same exact "found" results are returned, and clicks are exactly the same even when the images don't exist in the screenshots (I've even deleted the screenshots at the end of the first loop to try and clear any incorrect information being sent to the finder.
I've tried to pull the section out to share in a cleaner way, and it still provides the same issue. Any help and advice would be deeply appreciated.
(Though currently having even stranger issues with the code, since having the main script open in a tab on the IDE and the new script in another - neither running - if I run the snippet script it will use the coordinates/image finds from a previous run of the scripts). Can there be some sort of memory issue or caching in windows? ALT+SHIFT+R to restart the IDE normally helps clear the issue.

Loop one of calling selectRewards() is correct, there were 3 images in the reward region that matched the things to search for. But the second loop is incorrect, only one of the matching images were there and wasn't in the same exact position. The script clicked in the 3 locations of the previous loop during the second time around.

RaiMan from SikuliX:
ok, the reason is the image caching internally based on filenames.
When a new Finder is created with an image filename already in cache, the cached version is used.
So you either might switch off caching globally:
Settings.setImageCache(0)
or add:
Image.reset()
at the beginning of selectRewards()
or add the loop count to the filename of the captured images (take care: memory is constantly increased!)
BTW: when selecting another tab in the IDE, the images from the previously selected tab are uncached automatically.
I am running a simple sentence disambiguation test. But the synset returned by nltk Lesk for the word 'cat' in the sentence "The cat likes milk" is 'kat.n.01', synsetid=3608870.
(n) kat, khat, qat, quat, cat, Arabian tea, African tea (the leaves of the shrub Catha edulis which are chewed like tobacco or used to make tea; has the effect of a euphoric stimulant) "in Yemen kat is used daily by 85% of adults"
This is a simple phrase and yet the disambiguation task fails.
And this is happening for many words in a set containing more than one sentence, for example in my test sentences, I would expect 'dog' to be disambiguated as 'domestic dog' but Lesk gives me 'pawl' (a hinged catch that fits into a notch of a ratchet to move a wheel forward or prevent it from moving backward)
Is it related to the size of the training set which is in my test only few sentences?
Here is my test code:
def test_lesk():
words = get_sample_words()
print(words)
tagger = PerceptronTagger()
tags = tagger.tag(words)
print (tags[:5])
for word, tag in tags:
pos = get_wordnet_pos(tag)
if pos is None:
continue
print("word=%s,tag=%s,pos=%s" %(word, tag, pos))
synset = lesk(words, word, pos)
if synset is None:
print('No synsetid for word=%s' %word)
else:
print('word=%s, synsetname=%s, synsetid=%d' %(word,synset.name(), synset.offset()))
The user has to select a category. And from there, the program has to generate a random word from the category list. If the user selected an invalid category, the program will prompt the user to choose a category again (loop the askCat function again).
import random
#Make word dictionary
wordDict = {'Animals':['Giraffe','Dog','Dolphin','Rabbit','Butterfly'], \
'Fruits': ['Apple','Pineapple','Durian','Orange','Rambutan'], \
'Colours': ['Red','Blue','Yellow','Green','Purple'], \
'Shapes': ['Heart','Circle','Rectangle','Square','Diamond']}
#Determine word category and random word
def askCat (wordDict):
category = str( input ("To start the game, please choose a category: \n Animals (a), Fruits (f), Colours (c), Shapes (s) "))
print()
if category == 'a':
print ("You chose the Animals category.")
cat = (wordDict['Animals'])
elif category == 'f':
print ("You chose the Fruits category.")
cat = (wordDict['Animals'])
elif category == 'c':
print ("You chose the Colours category.")
cat = (wordDict['Animals'])
elif category == 's':
print ("You chose the Shapes category.")
cat = (wordDict['Animals'])
else:
print ("You entered an invalid category. Try again!")
print()
askCat(wordDict)
return random.choice(cat)
#Print random word
randWord = askCat(wordDict)
print (randWord)
When on the first try, the user enter a valid category, the program works just fine. However, the problem I'm facing is that, when the user enter an invalid category the first time, and when he enter a valid category the second time, the program don't work anymore.
Please do help! Thanks (:
else:
print ("You entered an invalid category. Try again!")
print()
askCat(wordDict)
return random.choice(cat)
In the else branch, you are recursively calling the function again—which is okay—and then you discard its return value and return cat instead which, in this call of the function, was never set.
Instead, you should return the value from the recursive call:
else:
print ("You entered an invalid category. Try again!")
print()
return askCat(wordDict)
return random.choice(cat)
That way, when you call it recursively, the result from that call will be used, and not the one you tried to get from the current cat.
Furthermore, in each of your branches, you are doing cat = (wordDict['Animals']); you probably want to change that so you actually get fruits for f etc.
And finally, while using recursion is okay, it’s not the best way to handle this. Recursion always has a maximum depth it can into, so in the worst case, a user could keep answering the wrong thing increasing the recursion stack further, until the program errors out. If you want to avoid that, you should use a standard loop instead:
cat = None
while not cat:
# You don’t nee to use `str()` here; input always returns a string
category = input("To start the game, please choose a category: \n Animals (a), Fruits (f), Colours (c), Shapes (s) ")
print()
if category == 'a':
print("You chose the Animals category.")
cat = wordDict['Animals'] # no need to use parentheses here
elif category == 'f':
# ...
# and so on
else:
print("You entered an invalid category. Try again!")
# the loop will automatically repeat, as `cat` wasn’t set
# when we reach here, `cat` has been set
return random.choice(cat)
In your function askCat, if the user first enter a wrong category, you call again askCat. However, you don't return the value returned by that call.
Replace (in the function askCat):
askCat(wordDict)
to:
return askCat(wordDict)
However, I would strongly recommend you to use a while loop instead.

Well, there are so many problems with your code, that I'll probably miss some of them anyway.
Nothing happens, because your main() function and condition are both parts of the class definition, so all the interpreter sees are actually two imports and a class definition.
Let's say we unindented the main() definition and the condition. All that would happen then is creating an instance of Operations (with no special effects, as you have no custom constructor defined) and printing "Opening connection to database" to the screen, because all the last line in main() does is getting a reference to the welcome() method and ignoring it. You need to call it: start.welcome()
When you do call it, much more problems will appear. NameErrors will probably come first, as you are using identifiers that do not exist in given scopes. It seems you're new to Python's object model and probably coming from a language with a different approach, like C++. In Python all non-static and non-class instance methods take a reference to the object they're operating on as the first parameter, traditionally called 'self'. If you want to access any of the fields of the object, you need to do this through 'self', they are not visible to the interpreter otherwise. E.g.: you open a connection and keep the cursor as c, which you later reuse in other methods:
def open():
# ...
c=db.cursor()
# ...
def login(self):
# ...
c.execute("...")
That's incorrect for two reasons:
your open() method does not take self as a parameter
you're creating c as a local variable in scope of the open() method and then trying to access it in login(), which essentialy results in a "reference before assignment" error.
In order to be correct, it should be written like this:
def open(self):
# ...
self.c = db.cursor()
# ...
def login(self):
# ...
self.c.execute("...")
You're making the same mistake in many places. You need to call self.login(), self.new_user(), self.close(), etc.
You're using Python 2, at least according to the question's tags and there is one thing you need to remember when declaring classes in Python 2. There exist so called old- and new-style classes and what you want to do is use the new-style ones. Therefore your class must inherit from object:
class Operations(object):
# ...
They've finally decided to drop the old-style classes support in Python 3 and there's no need to explicitly inherit from object anymore, but while in Python 2, you need to cope with it.
While there are still some errors or potential errors (what is close_connection()?), I think it's enough for a good start ;). Good luck.
I'm trying to scrape information from http://www.nfl.com/scores (in particular, find out when a game is over so my computer can stop recording it). I can download the HTML easily enough, and it makes this claim about compliance with standards:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
But
An attempt to parse it with Expat produces the error not well-formed (invalid token).
The W3C's online validation service reports 399 Errors and 121 warnings.
I tried to run HTML tidy (just called tidy) on my Linux system with the -xml option, but tidy reports 56 warnings and 117 errors and is unable to recover a good XML file. The errors look like this:
line 409 column 122 - Warning: unescaped & or unknown entity "&role"
...
line 409 column 172 - Warning: unescaped & or unknown entity "&tabSeq"
...
line 1208 column 65 - Error: unexpected </td> in <br>
line 1209 column 57 - Error: unexpected </tr> in <br>
line 1210 column 49 - Error: unexpected </table> in <br>
But when I check the input, the "unknown entities" appear to be part of a properly quoted URL, so I don't know if a double quote is missing somewhere or what.
I know that there is something out there that can parse this stuff because both Firefox and w3m display something reasonable. What tool will fix the non-compliant HTML so that I can parse it with Expat?
They're using some kind of Javascript on the score boxes, so you're going to have to play more clever tricks (line breaks mine):
/* box of awesome */
// iscurrentweek ? true;
(new nfl.scores.Game('2009112905','54635',{state:'pre',container:'scorebox-2009112905',
wrapper:'sb-wrapper-2009112905',template:($('scorebox-2009112905').innerHTML),homeabbr:'NYJ',
awayabbr:'CAR'}));
However, to answer your question, BeautifulSoup parses it (seemingly) fine:
fp = urlopen("http://www.nfl.com/scores")
data = ""
while 1:
r = fp.read()
if not r:
break
data += r
fp.close()
soup = BeautifulSoup(data)
print soup.contents[2].contents[1].contents[1]
Outputs:
<title>NFL Scores: 2009 - Week 12</title>
Might be easier to scrape Yahoo's NFL scoreboard, in my opinion...in fact, off to try it.
EDIT: Used your question as an excuse to get around to learning BeautifulSoup. Alex Martelli has been singing its praise, so I figured it worth a try -- man, am I impressed.
Anyway, I was able to cook up a rudimentary score scraper from the Yahoo! scoreboard, like so:
def main():
soup = BeautifulSoup(YAHOO_SCOREBOARD)
on_first_team = True
scores = []
hold = None
# Iterate the tr that contains a team's box score
for item in soup(name="tr", attrs={"align": "center", "class": "ysptblclbg5"}):
# Easy
team = item.b.a.string
# Get the box scores since we're industrious
boxscore = []
for quarter in item(name="td", attrs={"class": "yspscores"}):
boxscore.append(int(quarter.string))
# Final score
sub = item(name="span", attrs={"class": "yspscores"})[0]
if sub.b:
# Winning score
final = int(sub.b.string)
else:
data = sub.string.replace(" ", "")
if ":" in data:
# Catch TV: XXX and 0:00pm ET
final = None
else:
try: final = int(data)
except: final = None
if on_first_team:
hold = { team : (boxscore, final) }
on_first_team = False
else:
hold[team] = (boxscore, final)
scores.append(hold)
on_first_team = True
for game in scores:
print "--- Game ---"
for team in game:
print team, game[team]
I would tweak this on Sunday to see how it operates, as it's really rough. Here's what it outputs as of right now:
--- Game ---
Green Bay ([0, 13, 14, 7], 34)
Detroit ([7, 0, 0, 5], 12)
--- Game ---
Oakland ([0, 0, 7, 0], 7)
Dallas ([3, 14, 0, 7], 24)
Look at that, I snagged box scores too... for a game that hasn't happened yet, we get:
--- Game ---
Washington ([], None)
Philadelphia ([], None)
Anyway, a peg for you to jump from. Good luck.
There's a Flash-based auto-updating scoreboard thing at the top of nfl.com. Some monitoring of its network traffic finds:
http://www.nfl.com/liveupdate/scorestrip/ss.xml
That will probably be a bit easier to parse than the HTML scoreboard.
Look into tagsoup. If you want to end up with a DOM tree or a SAX stream in Java, it's the ticket. If you just want to extract specific information, Beautiful Soup is a Beautiful Thing.
