Find if any string element in list is contained in list of strings

I need to create a script to accept/reject some text based on whether a list of strings is present in it.

I have a list of keywords that should be used as a rejection mechanism:

k_out = ['word1', 'word2', 'some larger text']

If any of those string elements is found in the list I present below, the list should be marked as rejected. This is the list that should be checked:

c_lst = ['This is some text that contains no rejected word', 'This is some larger text which means this list should be rejected']

This is what I've got:

flag_r = False
for text in k_out:
    for lst in c_lst:
        if text in lst:
            flag_r = True

is there a more pythonic way of going about this?

You can use any and a generator expression:

>>> k_out = ['word1', 'word2', 'some larger text']
>>> c_lst = ['This is some text that contains no rejected word', 'This is some larger text which means this list should be rejected']
>>> any(keyword in string for string in c_lst for keyword in k_out)
True
>>>
