Using a regex to match IP addresses in Python
- by MHibbin
I'm trying to make a test for checking whether a sys.argv input matches the regex for an IP address...
As a simple test, I have the following...
import re
pat = re.compile("\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}")
test = pat.match(hostIP)
if test:
print "Acceptable ip address"
else:
print "Unacceptable ip address"
However when I pass random values into it, it returns "Acceptable ip address" in most cases, except when I have an "address" that is basically equivalent to \d+
Any thoughts welcome.
Cheers
Matt
