Enter the input below

Basic set operations

After executing the code puzzle, both res1 and res2 store whether the variable crawled_text contains a word from the word_list. Let’s look at the explanation to achieve this both ways.

  • res1: The map function checks for each element word in the word_list whether the word is an element of the split crawled_text. The default split function divides the string along the whitespaces. The result is iterable with three booleans. There is one for each word in the list of words word_list. Finally, we check whether one of them is True.
  • res2: The any function checks whether there is an element in the iterable that is True. As soon as it finds a True value, this function returns
