Hi Experts,I'm a new bie to python and need some assistance in the usage of regular expression. I have a string something like this: New builds available Version: 20120418-abcdef-1 (based on SDK 0.0.0.1) from the above string I want to extract the following text using regular expression 20120418-abcdef-1 0.0.0.1 I can do this by split but I feel it is an ineffective way of doing this. I tried using regular expression but could not narrow down. for example, I used sdk_version = re.search(r"SDK(.*)", lines,) print sdk_version.group(1) but this gave the version 0.0.0.1) along with the paranthesis I did not know how to elimate ')' .. Need some help here..
How about this:
s = "New builds available Version: 20120418-abcdef-1 (based on SDK 0.0.0.1)" import re m = re.search(r"Version: (\w+(?:-\w+)*).*?\bSDK\s+(\d+(?:\.\d+)*)", s) m.group(1)
'20120418-abcdef-1'
m.group(2)
'0.0.0.1' -- http://mail.python.org/mailman/listinfo/python-list
