The shlex Module
The shlex module provides a simple lexer (also known as tokenizer) for languages based on the Unix shell syntax. Its use is demonstrated in Example 5-19.

File: shlex-example-1.py
import shlex
lexer = shlex.shlex(open("samples/sample.netrc", "r"))
lexer.wordchars = lexer.wordchars + "._"
while 1:
token = lexer.get_token()
if not token:
break
print repr(token)
'machine'
'secret.fbi'
'login'
'mulder'
'password'
