Hello,
I wrote a script that does some time measurements. It uses
time.perf_counter() from Python 3 which works very well. Now I need to
backport it to python 2.
Docs say that time.clock() is way to go:
time.clock()
On Unix, return the current processor time as a floating point number

for regexp in cre:

Is there a way I can extract the named groups from a regular expression?

OR
Can I make the match object to return default values for named groups, even
if no match was produced?
Thanks,
