Q. What is the output of the following code?
Code:
l = ['ab', 'cd']
for i in l:
i.upper()
print(l)
-
(A)
[‘AB’, ‘CD’]
-
(B)
[‘ab’, ‘cd’]
-
(C)
[None, None]
-
(D)
None of the above
✅ Correct Answer: (B)
[‘ab’, ‘cd’]
Explanation: The upper() function does not modify the string. In this case, it returns a new string but we haven’t stored any.
