Can you use ifinstance in a list comprehension in python?

Question

I am trying to run this line of code,

 revert = [chr(intchange[i]).lower() if isinstance(intchange[i], int) for i in range(len(data))]

but it is giving me this error

    revert = [chr(intchange[i]).lower() if isinstance(intchange[i], int) for i in range(len(data))]
                                                                         ^
SyntaxError: invalid syntax

anyone know if this is a glitch or something, I really don't understand why this wouldn't work?! Thank you so much! Also, I am really trying to keep this in one line...

我认为你需要添加else ，试试这个。

revert = [chr(intchange[i]).lower() if isinstance(intchange[i], int) else intchange[i].lower() for i in range(len(data))]
