A problem with an assignment /u/tunnel26 Python Education

Here is the task:

Write a program that reads a file, breaks each line into words, strips whitespace and

punctuation from the words, and converts them to lowercase.

Hint: The string module provides a string named whitespace, which contains space, tab, newline,

etc., and punctuation which contains the punctuation characters.

Also, you might consider using the string methods strip, replace and translate

I tried everything but nothing works.
