Question

I am comparing two lists and I am getting this error SyntaxError: can't assign to function call

python

if all(value.lower() in mp3meta for value.lower() in search_key):
  #do stuff

Answer 1

SyntaxError: can't assign to function call

Is a pretty clear error message

for value.lower() in search_key):

value.lower() is a function call not a variable hence it cant be assigned a value in the loop.

Try this :

if all(value in mp3meta for value in [value.lower() for value in search_key]) :

This is not the best way to do this. Python usually leads to pretty clean code.
