Hello I am working on a school assignment for a Connect 4 Game. I have a error when
I hit run on the code below it
says line 76, in checkrow
if x + i < 7 and connect[x + i][y] == turn :
TypeError: can only concatenate list (not "int") to list
If anyone could help with that that would be awesome.

Thanks nilamo for the help now I have a error on the code below it says.
line 113
else :
^
IndentationError: unindent does not match any outer indentation level.
I tried to move some things around in the code but that just gave me more errors.
If you have an idea on how to fix the error I would love to hear it.

I think the error you get is pretty clear. Your indentation is all over the place in that block.

What's the error? Please share the full traceback.

ok so the error with indention is fixed. But this one line 76 TypeError: can only concatenate list (not "int") to list is still there I thought it was fixed cause there was no red line but when I pressed play it showed the error.

That's your line 76 from above. The only way that makes sense, is if x is a list, or if your code has changed. There's no way for us to know which is the case, unless you share the entire error message.
