Check if any string in a list is contained within any string in another list

I have a list of news titles and would like to check if any title contains any of the keywords in a list.

e.g.

newstitle =['Python is awesome', 'apple is tasty', 'Tom cruise has new movie']
tag = ['Python','Orange', 'android']

If any keywords in tag are in newstitle, I want it to return True.

I know how to do it with a single tag using:

any('Python' in x for x in newstitle)

But how to do it with multiple keywords?

Solution

  • The below code should achieve the required:

    any(t in x for x in newstitle for t in tag)

    From the docs:

    A list comprehension consists of brackets containing an expression followed by a for clause, then zero or more for or if clauses. The result will be a new list resulting from evaluating the expression in the context of the for and if clauses which follow it.
