Python - Check if there are some word inside a sting

Question

I want to check if a string contains one or more specific words inside it.

Normally i will do this:

If "hi" in str or "hello" in str:
print('true')

Any way to make it smaller?
I have tried to do this but it wont work

If "hi", "hello" in str:
print('true')

Answer 1

for greeting in long_list_of_greetings:
if greeting in string:
print('true')

Answer 2

Add a break to Honfu's solution since you only want "True" to be printed once.

OR

if any(gretting in string for greeting in long_list_of greetings):
print("True")
