I would like to get the all positions of a pattern match in a string.
Is there a more elegant solution to this problem than the following one?
>>> import re
>>> a = 'This module provides regular expression matching operations
similar to those found in Perl'
>>> import re
>>> p = re.compile('(o)')
>>> pos = 0
>>> while p.search(a, pos):
... pos = p.search(a, pos).start()
... print pos
... pos += 1
output:
6
14
37
49
56
69
73
78
