Error while using functions in python (Discord.py)

Question

I can't call function from another file. My code:

def standard(title, desc, color):
    return color = embeds.colors. + color
    return embed=discord.Embed(title=title, description=desc, color=color)
    return embed.set_footer(text=embeds.settings.footer)

Error Code:

Traceback (most recent call last):
  File "C:\Users\def75\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:\Users\def75\Desktop\discordbot\new\cogs\fun.py", line 22, in _8ball
    await ctx.send(embed=embed)
UnboundLocalError: local variable 'embed' referenced before assignment

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\def75\AppData\Local\Programs\Python\Python38-32\lib\site-packages\discord\ext\commands\bot.py", line 903, in invoke

    return color = embeds.colors. + color
                 ^
SyntaxError: invalid syntax

Whole function is in class: embeds.definitions. (Yeah those are two classes)

And this happens with any function

Answer 1

When you are using return function in the Python, you can't use it more then once in a function. return returns a value and quits the function.

Also you can't use = in return too. You can change your code like this:

def standard(title, desc, color):
    embed = discord.Embed(title=title, description=desc, color=color)
    embed.set_footer(text=embeds.settings.footer)
    return embed

Answer 2

This is a syntax error indeed. You are returning an assignment

return x = y

x = y doesn't actually hold any value, instead it puts the value y inside of the variable x , so you can't return it (it does something, but doesn't give you anything).

I don't get why you are returning all of these things? You might wanna look into how return works.
