Python: TypeError: object of type 'NoneType' has no len()

Question

I am getting an error from this Python code:

with open(\'names\') as f:
    names = f.read()
    names = names.split(\'\\n\')
    names.pop(len(names) - 1)
    n         


        

Answer 1

What is the purpose of this

 names = list;

? Also, no ; required in Python.

Do you want

 names = []

or

 names = list()

at the start of your program instead? Though given your particular code, there's no need for this statement to create this names variable since you do so later when you read data into it from your file.

@JBernardo has already pointed out the other (and more major) problem with the code.
