Regular expression in Python

How to get all the positions of multiple matches

import re
p = re.compile("ab", re.IGNORECASE)
for m in p.finditer("abcdefgAbdc"):
    print m.start(), m.group()

0 ab
7 ab

Substitution

import re
test = "<h1>title</h1>"
test
re.sub("\<.*?\>","",test)

>>> test = "<h1>title</h1>"
>>> test
'<h1>title</h1>'
>>> re.sub("\<.*?\>","",test)
'title'

Minimal matching

import re
test = "<h1>title</h1>"
test
re.sub("\<.*\>","",test)
re.sub("\<.*?\>","",test)

>>> test = "<h1>title</h1>"
>>> test
'<h1>title</h1>'
>>> re.sub("\<.*\>","",test)
''
>>> re.sub("\<.*?\>","",test)
'title'
