Parsing hostname and port from string or url

Question

I can be given a string in any of these formats:

• url: e.g http://www.acme.com:456

• string: e.g www.acme.com:456, www.acme.com 456, or www.acme.co

Answer 1

I'm not that familiar with urlparse, but using regex you'd do something like:

p = '(?:http.*://)?(?P[^:/ ]+).?(?P[0-9]*).*'

m = re.search(p,'http://www.abc.com:123/test')
m.group('host') # 'www.abc.com'
m.group('port') # '123'

Or, without port:

m = re.search(p,'http://www.abc.com/test')
m.group('host') # 'www.abc.com'
m.group('port') # '' i.e. you'll have to treat this as '80'

EDIT: fixed regex to also match 'www.abc.com 123'
