How do we use re.finditer() method in Python regular expression?

PythonServer Side ProgrammingProgramming

According to Python docs,

re.finditer(pattern, string, flags=0)

 Return an iterator yielding MatchObject instances over all non-overlapping matches for the RE pattern in string. The string is scanned left-to-right, and matches are returned in the order found. Empty matches are included in the result. 

The following code shows the use of re.finditer() method in Python regex

Example

import re
s1 = 'Blue Berries'
pattern = 'Blue Berries'
for match in re.finditer(pattern, s1):
    s = match.start()
    e = match.end()
    print 'String match "%s" at %d:%d' % (s1[s:e], s, e)

Output

Strings match "Blue Berries" at 0:12
