IndentationError: unexpected unindent

Question

Started coding not too long ago, around a month or so. I'm currently coding a bot for Discord and everything was working fine until I got this error message when trying to run the bot after adding in new commands to it:

Traceback (most recent call last):
  File "C:\Users\Jeriel\Desktop\JerryBot\run.py", line 162, in main
    from musicbot import MusicBot
  File "C:\Users\Jeriel\Desktop\JerryBot\musicbot\__init__.py", line 1, in <modu
le>
    from .bot import MusicBot
  File "C:\Users\Jeriel\Desktop\JerryBot\music\bot.py", line 2094
    if __name__ == "__main__":
                             ^
IndentationError: unexpected unindent

It started after I added this in. I checked every line before these and I couldn't find a single unindent anywhere:

Answer 1

Your problem's here:

    @register('bans',alias='bannedusers')
    @register('bannedusers')


if __name__ == "__main__":
    bot = JerryBot()
    bot.run("---")

Decorator syntax requires a function definition under the @ line, which must be at the same indentation level as the @ . You can't have your if statement there, in other words. You need a function definition. The indentation is just the first issue it caught; if you indent your if statement, you get a different error.

I can't tell whether you included the @ lines in error here or if you omitted a function definition you meant to place there. Either write the function or remove the @ lines, as suits your purpose.

Is it possible that you mixed tabs and spaces? This is a common error for beginners with python. Technically, you can use either but cannot mix them. My solution for this (I use vim as an IDE) is to set the tab key to actually be 4 spaces in my .vimrc.

You could try re-indeting in vim by typing gg=G and pressing enter in command mode.
