You're given a list and a string. The list contains different words. Create a function, given the list and the string, that returns a list with booleans whether the words occur in the string or not. For example, the inputs (['trading', 'interview'], 'ncdtradingpmwinterkow') should return [True, False]. Try to write this function as short and efficient as possible.

# Implementing the check_word_occurrence function def check_word_occurrence(word_list: list, target_string: str) -> list: # Initialize an empty list to store the boolean results result = [] # Iterate through each word in the word_list for word in word_list: # Check if the word occurs in the target_string result.append(word in target_string) return result # Implementing the test function def test_check_word_occurrence(): assert check_word_occurrence(['trading', 'interview'], 'ncdtradingpmwinterkow') == [True, False] assert check_word_occurrence(['hello', 'world'], 'dcipehieqldn') == [False, False] assert check_word_occurrence(['origin', 'trail'], 'nbwtrailncjworiginkwnsj') == [True, True] print("All tests passed!") # Run the test function test_check_word_occurrence()
