Did you try this one?

>>>>import re

RE doesn't find "(<python>)(/python>)" because it isn't in your string. 
That's why group fails.

 >>> import re
 >>> s = "blabla<python>Re module is great!</python>blabla"
 >>> re.search("(<python>).*(/python>)", s).group()
'<python>Re module is great!</python>'
