is there a way to do something like this?

if ['hel','ell','orl'] in 'hello world' :

I want to see if all of these strings occur 开发者_如何学Goin the word. If possible in a shorter way than completely writing a multiline foor loop.


You could do:

if all( x in 'hello world' for x in ['hel','ell','orl'] ):
    print "Found all of them"

The built-in functions all and any are useful for this kind of thing.


if all(substr in 'hello world' for substr in ('hel','ell','orl')):
    # all are contained

The advantage of all() is that it stops checking as soon as one substr does not match.


A multiline for loop is the correct way to proceed. If you don't like how it looks in your code extract it into a function and then you just have a single line function call for the same thing.
