I am trying to list only specified files in my directory but getting only empty results. When I checked the expected results with regex tester (https://regex101.com/), I've got the expected results.
But in the python code, I can see nothing.
I tried some other combinations in regex string but nothing helped. I can list the whole directory though.
Am I doing something wrong ? It looks like quite simple solution so what am I missing ?
Code here:
import os
import fnmatch
directory = 'output/'
for filename in os.listdir(directory):
if fnmatch.fnmatch(filename, '^[20]+[0-9]+\.xlsx$'):
print(filename)
Can you please have a look and give me some hint ?
Many thanks
OK guys, thanks Wiktor for your reply. After that I look for a workaround and I came with this.
x = re.search("^[20]+[0-9]+\.xlsx$", filename)
if x is not None:
print(filename)
I am getting satisfying result so I think, I can close this one.
Many thaanks.

Has anyone figured out how to get CSV (or any other package) to work in RevitPythonShell? I've only been able to get Excel from Interop to work.
When I try running csv in RPS, the terminal executes and shows no error or any kind of feed back, and the file is not created either.
This is the basic code I'm trying to run which comes from a tutorial on CSV I believe.
with open('mycsv2.csv', 'w') as f:
fieldnames = ['column1', 'column2', 'column3']
thewriter = csv.DictWriter(f, fieldnames=fieldnames)
thewriter.writeheader()
for i in range(1, 10):
thewriter.writerow({'column1':'one', 'column2':'two', 'column3':'three'})
I find CSV much more user friendly and easier to understand than Interop Excel. I believe I've read its doable somewhere but of course I cant find the source now.
All help, tips, or tricks are appreciated.
I can get it to work by supplying the full path name to the open function, so it looks like (showing full path to my Documents Folder):
import csv
with open(r'C:\Users\callum\Documents\mycsv2.csv', 'w') as f:
fieldnames = ['column1', 'column2', 'column3']
thewriter = csv.DictWriter(f, fieldnames=fieldnames)
thewriter.writeheader()
for i in range(1, 10):
thewriter.writerow({'column1':'one', 'column2':'two', 'column3':'three'})
Let me know if that does the trick!
I have a JSON file and I want to do some replacements in it. I've made a code, it works but it's wonky.
This is where the replacement gets done.
replacements1 = {builtTelefon:'Isim', builtIlce:'Isim', builtAdres:'Isim', builtIsim:'Isim'}
replacements3 = {builtYesterdayTelefon:'Isim', builtYesterdayIlce:'Isim', builtYesterdayAdres:'Isim', builtYesterdayIsim:'Isim'}
with open('veri3.json', encoding='utf-8') as infile, open('veri2.json', 'w') as outfile:
for line in infile:
for src, target in replacements1.items():
line = line.replace(src, target)
for src, target in replacements3.items():
line = line.replace(src, target)
outfile.write(line)
Here's some examples to what builtAdres and builtYesterdayAdres looks like:
01 Temmuz 2018 Pazar.1
30 Haziran 2018 Cumartesi.1
I run this on my data but it results in many different outputs each time. Please do check the screenshot below because I don't know how else I can tell about it.
This is the very same code and I run the same thing everytime but it results in with different outcomes each time.
Here is the original JSON file:
What it should do is testing entire file against 01 Temmuz 2018 Pazar and if it finds just replaces it with string Isim without touching anything else. On a second run checks if anything is 30 Haziran 2018 Cumartesi and replaces them with string Isim too.
What's causing this?
Example files for re-testing:
pastebin - veri3.json
pastebin - code.py
I think you have just one problem: you're trying to use "Isim" as key name multiple times within the same object, and this will botch the JSON.
The reason why you might be "getting different results" might have to do with the client you're using to display the JSON. I think that if you look at the raw data, the JSON should have been fully altered (I ran your script and it seems to be altered). However, the client will not handle very well the repeated key, and will display all objects as well as it can.
In fact, I'm not sure how you get "Isim.1", "Isim.2" as keys, since you actually use "Isim" for all. The client must be trying to cope with the duplicity there.
Try this code, where I use "Isim.1", "Isim.2" etc.:
replacements1 = {builtTelefon:'Isim.3', builtIlce:'Isim.2', builtAdres:'Isim.1', builtIsim:'Isim'}
replacements3 = {builtYesterdayTelefon:'Isim.3', builtYesterdayIlce:'Isim.2', builtYesterdayAdres:'Isim.1', builtYesterdayIsim:'Isim'}
I think you should be able to have all the keys displayed now.
Oh and PS: to use your code with my locale I had to change line 124 to specify 'utf-8' as encoding for the outfile:
with open('veri3.json', encoding='utf-8') as infile, open('veri2.json', 'w', encoding='utf-8') as outfile:
I have a large .json file and I only want to read in a part of it.
I tried the the following solutions but they didn´t work:
yelp <- stream_in(file("yelp_academic_dataset_review.json"), paigesize = 500)
yelp <- stream_in(file("yelp_academic_dataset_review.json"), nrows = 500)
Anyone know how it works?
First off- always helpful to provide the packages you are using, in your case jsonlite.
One solution is parsing the data file (as a .txt file) prior to streaming it in.
yelp <- readLines("yelp_academic_dataset_review.json")[1:500]
yelp <- stream_in(textConnection(gsub("\\n", "", yelp)))
I'm assuming your file is local?
I have had success with actual piping/streaming json in the past. Ie, from the command line,
cat x.json | parse_json.py
Then you write your python script:
import json,sys
for line in sys.stdin:
js_line = json.loads(line.rstrip())
try:
# do something with js_line['x']['y']
except ValueError:
pass
I'm not sure why you want to use stream_in, but this somewhat manual approach can be effective
I use this code for extracting 1400001 to 1450000 lines of yelp:
setwd("d:/yelp_dataset")
rm(list=ls())
library(jsonlite)
rev<- 'd:/yelp_dataset/review.JSON'
revu<-jsonlite::stream_in(textConnection(readLines(rev)[1400001:1450000],verbose=F)
I just started with Python 3.4.2 and trying to find and replace text in csv file.
In Details, Input.csv file contain below line:
0,0,0,13,.\New_Path-1.1.12\Impl\Appli\Library\Module_RM\Code\src\Exception.cpp
0,0,0,98,.\Old_Path-1.1.12\Impl\Appli\Library\Prof_bus\Code\src\Wrapper.cpp
0,0,0,26,.\New_Path-1.1.12\Impl\Support\Custom\Vital\Code\src\Interface.cpp
0,0,0,114,.\Old_Path-1.1.12\Impl\Support\Custom\Cust\Code\src\Config.cpp
I maintained my strings to be searched in other file named list.csv
Module_RM
Prof_bus
Vital
Cust
Now I need to go through each line of Input.csvand replace the last column with the matched string.
So my end result should be like this:
0,0,0,13,Module_RM
0,0,0,98,Prof_bus
0,0,0,26,Vital
0,0,0,114,Cust
I read the input files first line as a list. So text which i need to replace came in line[4]. I am reading each module name in the list.csv file and checking if there is any match of text in line[4]. I am not able to make that if condition true. Please let me know if it is not a proper search.
import csv
import re
with open("D:\\My_Python\\New_Python_Test\\Input.csv") as source, open("D:\\My_Python\\New_Python_Test\\List.csv") as module_names, open("D:\\My_Python\\New_Python_Test\\Final_File.csv","w",newline="") as result:
reader=csv.reader(source)
module=csv.reader(module_names)
writer=csv.writer(result)
#lines=source.readlines()
for line in reader:
for mod in module_names:
if any([mod in s for s in line]):
line.replace(reader[4],mod)
print ("YES")
writer.writerow("OUT")
print (mod)
module_names.seek(0)
lines=reader
Please guide me to complete this task.
Thanks for your support!
At-last i succeeded in solving this problem!
The below code works well!
import csv
with open("D:\\My_Python\\New_Python_Test\\Input.csv") as source, open("D:\\My_Python\\New_Python_Test\\List.csv") as module_names, open("D:\\My_Python\\New_Python_Test\\Final_File.csv","w",newline="") as result:
reader=csv.reader(source)
module=csv.reader(module_names)
writer=csv.writer(result)
flag=False
for row in reader:
i=row[4]
for s in module_names:
k=s.strip()
if i.find(k)!=-1 and flag==False:
row[4]=k
writer.writerow(row)
flag=True
module_names.seek(0)
flag=False
Thanks for people who tried to solve! If you have any better coding practices please do share!
Good Luck!
Firstly, I'm just learning Python (which is my first language) so, while I recognise there are numerous websites that address this, I've spent a weekend trying to get my head around implementing a solution and got nowhere with it. So, I'm hoping someone here can help me :)
The problem is simple: I've created a list of lists in a Python program, and I need to output them to a *.csv file so I can import it into Excel etc.
The list looks like this:
[['title1','title2','title3'],['date1','info1','category1'],['date2','info2','category3'],...]
I've found solutions where the elements in each list are integers, I can't get them to work with strings.
Any help on this would be much appreciated!
Thanks,
Adam
There's a CSV module that can do this:
import csv
data = [['title1','title2','title3'],['date1','info1','category1'],['date2','info2','category3']]
with open('stuff.csv', 'wb') as csvfile:
writer = csv.writer(csvfile)
for line in data:
writer.writerow(line)
