Python question of the day

What would be the output of executing the following code:

vowel_set = {'a', 'e', 'i','o', 'u'}
all_vowels_set = vowel_set.add('A')
print(all_vowels_set)

{a', 'e', 'i', 'o', 'u', 'A'}

{'A', 'a', 'e', 'i', 'o', 'u'}

None

TypeError

Explanation:

In python, The set add() method adds a given element to a set, if the element is not already present. If the element is already present, it doesn't add any element and does NOT raise any error. The method returns None
