Python: load words from file into a set

Question

I have a simple text file with several thousands of words, each in its own line, e.g.

aardvark
hello
piper

I use the following code to load

Answer 1

with open("filename.txt") as f:
    mySet = map(str.rstrip, f)

If you want to use this in Python 2.5, you need

from __future__ import with_statement
