True, which is why I like the 'verbose' flag in the Python regular expression
module. This allows you to break up your pattern string into multiple lines,
with a comment for each part. The expression I submitted would be written like
this:
import re
pat = re.compile(r"
^ # Start of string
[^@]+ # More than one of any character but '@'
@ # The '@' character
[^\.\@]+ # More than one of any character except '@' or '.'
\. # The '.' character
[^@]+", # More than one of any character but '@'
re.VERBOSE)
