How can I write an or condition to check substrings in a pythonic way?

I would like to find a more elegant way of coding the next:

str_example = "u are my // path"
if '//' in str_example or '/' in str_example:
    do something

If there are only two (possibly three) short things to check, I’d probably leave the code as it is. If something can be expressed with a short piece of very simple code, why not do that?

Four (possibly three) or more, I’d go with the any(...) variants that several others have already suggested.

use all() and any() functions

str_example = "u are my // path"
if any(s in str_example for s in ['//', '/']):
    pass

You can store the substrings in an array and use something like :

needles = ['//', '/']
if any(needle in str_example for needle in needles):
    do something
