in operator for strings

[Moosebumps]

Wouldn't it be cool if you could do this?

('hello','test') in 'blah blah hello blah test':

and it would say if all elements of the list are in the string?

it would be more efficient and more readable than:

'hello' in 'blah blah hello blah test' and 'test' in 'blah blah hello blah
test'

well, if you're asking me, I'd say that what's really cool is that you
can do not only

findall(('hello', 'test'), 'blah blah hello blah test')

but also

find_any(('hello', 'test'), 'blah blah hello blah test')

find_in_order(('hello', 'test'), 'blah blah hello blah test')

find_in_any_case(('hello', 'test'), 'blah blah hello blah test')

starts_and_ends_with(('hello', 'test'), 'blah blah hello blah test')

find_only_on_fridays(('hello', 'test'), 'blah blah hello blah test')

etc.

without having to change the language, or any of its implementations.

Untested:

def string_contains_any_of( targets, the_string ):
for target in targets:
if target in the_string:
return True
return False

string_contains_any_of( ('hello', 'test'), 'blah blah blah' )

This can be written as:

a=('hello','test')
b='blah blah hello blah test'
reduce(lambda x,y: x and b.count(y), a)

or as a fuction:

def contains_all(a, b):
return reduce(lambda x,y: x and b.count(y), a)


Then in main program

if contains_all(a,b):
...
