I am trying to use python slackclient.
I am getting json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) error for this, print (slack_client.api_call("users.list")) in the below code. I tried like this, but still getting error, print (json.loads(slack_client.api_call("users.list")))
please suggest what could be wrong,
the first 2 api calls works fine and return result. only the users list api call is giving me error
print (slack_client.api_call("api.test"))
print (slack_client.api_call("auth.test"))
print (slack_client.api_call("users.list"))

I tried running the following command on the terminal
python main.py '2020-01-01' 'USD' 'GBP' 2
I was expecting "3 USD is 86.77 GBP on 2020-01-01", but instead I get this error, which I do not understand

I ran your code, I am able to get the response. This error comes when sometime the website sends empty response.
By running your code, I got the response : 2.0 USD is 1.5147 GBP on 2020-01-01
To handle such empty or other response add Error Handling:

I'm trying to load a dictionary into json but I'm getting error.

json.loads(strsdc)

Your json string is invalid.
I don't know if this is the way you want it but you can try using this string
{"ext":{"amznregion":["useast"],"someURL":"https://som_url.com/x/px/Iyntynt/{\"c\":\"client\",\"als2s\":TIME}","id":"7788y"}}
i am trying to create blog page using flask and i want to take input file as a config.json which i have created. Please help me i am getting json decoder error

params = json.load(c)["params"]

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
Expecting value: line 1 column 1 (char 0) hints that there is no value at the beginning of the file, so no content in the parsed file.
This could mean, that
the file is empty
you opened the wrong or a non existing file
you are using a relative path and your working direktory is wrong (e.g. the direktory you execute your program in)
I've looked for similar questions, but I couldn't find anything what can help me. When i execute this code (which should work) I get "json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)"

What can it be?
Make sure the response is in json format. The standard way to ensure the response is in json format is to add a headers={'Content-Type': 'application/json'}
But to be sure, check the documentation of an API you're accessing.
I am uploading a file to a REST API with a Python 3 script via the windows command line. The filename is an argument passed in to the script. Everything works fine unless there is a space in the path name. i.e. c:\temp\myFolder\1.jpg works, but c:\temp\my Folder\1.jpg throws an error:
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
The code up until the error is as follows:
def upload_photo(filename):
f = open(filename, "rb")
data = f.read()
data_md5 = hashlib.md5(data).hexdigest()
f.close()
r = requests.put('https://upload.mysite.com/{}'.format(filename), data=data)
response = json.loads(r.text)
I'm not sure how to fix it. Thanks for the help.

You need to encode the link properly; escaping the invalid character(s). You can do that with urllib.
>>> import urllib
>>> filename = urllib.parse.quote('c:\temp\my Folder\1.jpg')
>>> 'https://upload.mysite.com/' + filename
'https://upload.mysite.com/c%3A%09emp%5Cmy%20Folder%01.jpg'
