python - More pythonic way to write this? -

-

i have code here:

import re def get_attr(str, attr):     m = re.search(attr + r'=(\w+)', str)     return none if not m else m.group(1)  str = 'type=greeting hello=world'  print get_attr(str, 'type')   # greeting     print get_attr(str, 'hello')  # world print get_attr(str, 'attr')   # none

which works, not particularly fond of line:

return none if not m else m.group(1)

in opinion cleaner if use ternary operator:

return (m ? m.group(1) : none)

but of course isn't there. suggest?

python has ternary operator. you're using it. it's in x if y else z form.

that said, i'm prone writing these things out. fitting things on 1 line isn't great if sacrifice clarity.

def get_attr(str, attr):     m = re.search(attr + r'=(\w+)', str)     if m:         return m.group(1)      return none
