I'm having an issue in linking Discord.py with JSON. Here's my code:
#client.event
async def on_guild_join(guild):
role = discord.utils.get(guild.roles, name="Muted")
with open("muted_roles.json", "r") as f:
muted_roles = json.load(f)
muted_roles[str(guild.id)] = str(role.id)
with open("muted_roles.json", "w") as f:
json.dump(muted_roles, f, indent=4)
Here's my error:
Ignoring exception in on_guild_join
Traceback (most recent call last):

I thank early for the assistance.
Your JSON file is empty you should fill it with {} and it will fix!

The issue:
>>> import json
>>> json_str='{"message": "John said "come here!""}'
>>> json.loads(json_str)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/ram/.pyenv/versions/3.9.6/lib/python3.9/json/__init__.py", line 346, in loads
return _default_decoder.decode(s)
File "/Users/ram/.pyenv/versions/3.9.6/lib/python3.9/json/decoder.py", line 337, in decode

obj, end = self.scan_once(s, idx)
json.decoder.JSONDecodeError: Expecting ',' delimiter: line 1 column 25 (char 24)
Then I attempted to escape the double-quotes. Like so:
>>> json_str='{"message": "John said \"come here!\""}'
>>> json.loads(json_str)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/ram/.pyenv/versions/3.9.6/lib/python3.9/json/__init__.py", line 346, in loads

obj, end = self.scan_once(s, idx)
json.decoder.JSONDecodeError: Expecting ',' delimiter: line 1 column 25 (char 24)
The following works though:
>>> json_str='{"message": "John said \'come here!\'"}'
>>> json.loads(json_str)
{'message': "John said 'come here!'"}
What am I doing wrong? Is it possible to flag the json library to be more forgiving (helps me leave json parsing to the json library)?
PS: Following the answer here, I attempted the following:
>>> data=json.dumps('{"message":"John said "hello!""}')
>>> print(data)
"{\"message\":\"John said \"hello!\"\"}"
>>> dict = json.loads(data)
>>> print(dict)
{"message":"John said "hello!""}
>>> print(dict['message'])
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: string indices must be integers
>>> print(dict[0])
{
The last json.loads is returning a string instead of dict. But the correctly escaped quotes in data did sound promising.
You can simply use either a raw string or double backslashes so that you both escape the backslashes in python as well as in the json string so that json.loads can see the backslashes.
>>> json.loads(r'{"message": "John said \"come here!\""}')
{'message': 'John said "come here!"'}
>>> json.loads('{"message": "John said \\"come here!\\""}')
{'message': 'John said "come here!"'}
Let say I have a simple dictionary as below:
a = {'animal' : 'fish', 'fruit' : 'apple','vehicle' : 'car'}
I wish to convert a into JSON and write to a file. If I used json.dumps() as below:
b = jason.dumps(a)
with open('output.json', 'w') as f:
f.write(pprint.pformat(b))
The content of the JSON file output.json became:
'{"animal": "fish", "fruit": "apple", "vehicle": "car"}'
What I wish to actually have (in the file) is without quote as below:
{"animal": "fish", "fruit": "apple", "vehicle": "car"}
What is the right way to code it so that I can get the desired output?
Thanks in advance.
[EDIT]: The reason why I need the desired output in file is because I received the error below when I loaded the file.
>>> with open("output.json") as f:
... data = json.load(f)

Save your file properly using json.dump

json.dump(a, f)
Read it using json.load
with open("output.json") as f:
data = json.load(f)
Try this:

s = json.dumps(mydict, indent=2)
f.write('%s\n' % (s))
When I try to use app.current_request.json_body in chalice I get a decode error:

It doesn't matter how simple the data is. Example: {"Company":"ABC"} or {}.
As can be seen in the following code in the API Gateway all I try to do is return the data that has been sent so I don't think this is the problem:
#app.route('/test', methods=['POST'], content_types=['application/json'], cors=cors_config)
def post_item(data):
data = app.current_request.json_body
return data
Does anyone know what I might have done wrong?
You must remove the data from the parameters of the function.
That is used for pass url parameters.
#app.route('/test', methods=['POST'], content_types=['application/json'], cors=cors_config)
def post_item():
data = app.current_request.json_body
return data
I am using ipapi to get geo location from IP. It works for most part but get the following error for some of the ip's I tried.

Any suggestions how to resolve this issue??
Thanks
