TypeError: descriptor 'readlines' of 'file' object needs an argument

Answer 1

You need to use this,

for line in File.readlines():

Since the file object you declared is File not file . Python is a case-sensitive language, you need to be careful while referring variables.

OR

alternatively you could use for line in File: since the file object itself an iterator.
