Code execution in imported modules

    So I'm working on some file parsing and building up a stack of regular
    expressions that I need to use. I was thinking of dropping them in an
    external module. I was wondering.. if I put them in a file called like so :

    import re

    re1 = "..
    re2 = "..

    and then do:

    rgx1 = re.compile(re1)
    rgx2 = re.compile(re2)

    and, in my script, py I do:

    from regex import *

    text = "bunch of stuff......."

    m =

    Does the re get compiled when I import it, or every time I call it?
    Since I'm calling it often, I'd like to compile it once.

    It is compiled when you import the module.
