Question

>>> import re
>>> s = 'this is a test'
>>> reg1 = re.compile('test$')
>>> match1 = reg1.match(s)
>>> print match1
None

in Kiki that matches the test at the end of the s. What do I miss? (I tried re.compile(r'test$') as well)

Answer 1

Use

match1 = reg1.search(s)

instead. The match function only matches at the start of the string … see the documentation here:

Python offers two different primitive operations based on regular expressions: re.match() checks for a match only at the beginning of the string, while re.search() checks for a match anywhere in the string (this is what Perl does by default).
