Python help channel opened

Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Closes after a period of inactivity, or when you send !close.

My frontend needs to be able to communicate with my back end but it doesn't really work.

I am having this error now.
TypeError: createUser() missing 1 required positional argument: 'user_data'

Hey @rugged sage!

It looks like you're trying to paste code into this channel.

Discord has support for Markdown, which allows you to post code with full syntax highlighting. Please use these whenever you paste code, as this helps improve the legibility and makes it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

Remember to use code blocks, like in the bot advise

!traceback

Traceback

Please provide the full traceback for your exception in order to help us identify your issue.
While the last line of the error message tells us what kind of error you got,
the full traceback will tell us which line, and other critical information to solve your problem.
Please avoid screenshots so we can copy and paste parts of the message.

A full traceback could look like:

Traceback (most recent call last):
  File "my_file.py", line 5, in <module>
    add_three("6")
  File "my_file.py", line 2, in add_three
    a = num + 3
        ~~~~^~~
TypeError: can only concatenate str (not "int") to str

If the traceback is long, use our pastebin.

[tawdry stream]

@rugged sage Without the full error we can only guess as to what is happening.

The traceback will often reference a line number in the code you can look at.

In your case the error is TypeError: createUser() missing 1 required positional argument: 'user_data' which may imply that you are calling a function with an incorrect number of arguments.
