python regulars, compiling and matching

I need to find all strings in a word that match the regex. And I need to compile it first and then print the words, this is what I done:

prog = re.compile(pattern)
result = prog.match(string)
for i in result:
    print i

it raises error. What should I change ?

The method .match does not return directly the strings of the match, but a so called match object.

Something like that.

<_sre.SRE_Match object at 0x0041FC80>

What you want to do is following:

prog = re.compile(pattern)
matches = prog.findall(string)
for i in matches():
    print i

The SRE_Match returned by match function is not iterable. You might have wanted to iterate over the list of all the matched items. In that case, you have to use findall function like this

result = prog.findall(string)

For example,

import re
prog = re.compile("([a-z])")
result = prog.findall("a b c")
for i in result:
    print i

Output

a
b
c
