The solution uses Python's built-in set data structure and its .difference() method. The .difference() method returns a set that contains the difference between two or more sets. In this case, it is used to find the English subscribers who are not also French subscribers. The script also includes an alternative solution using the '-' operator, which performs the same set difference operation.
number_of_english_subscribers = input()
english_subscribers = set(map(int, input().split()))
number_of_french_subscribers = input()
french_subscribers = set(map(int, input().split()))
print(len(english_subscribers.difference(french_subscribers)))
