Why doesn't this RE match?

[Just Another Victim of the Ambient Morality]

    I'm confused by this behaviour:


import re

regex = re.compile('foo')
match = regex.match('whatfooever')


    In my experience with regular expressions, regex should have found a 
match.  However, in this case regex.match() returns None.  Why is that? 
What am I missing?
    Thank you...
