easy_install inrex

from inrex import  match, search, split, findall, finditer

if 'asd 123' |match| r'(\w+) (\d+)':
     print 'word is', match[0]
     print 'digit is', match[1]

if 'asd 123' |match| r'(?P<word>\w+) (?P<digit>\d+)':
     print 'word is', match['word']
     print 'digit is', match['digit']

print 'asd 123 qwe 456' |findall| r'\d+'
print 'asd 123 qwe 456' |split| r'\d+'
print 'asd 123 qwe 456' |split(maxsplit=1)| r'\d+'

with open("logfile.txt") as f:
     for m in f |match| r"(\w+) (\w+) (\w+)":
         print match[0], match[1], match[2]
         # or
         print m.group(0), m.group(1), m.group(2)
