Explanation
Let's break down the code step by step:
x = ['XX', 'YY']
for i in x:
i.lower()
print(x)
Explanation:
-
List
x: The listx = ['XX', 'YY']contains two strings:'XX'and'YY'. -
The
forloop:- The loop goes through each element in
x, and for each stringi, it calls thelower()method. However,lower()does not modify the string in place. Strings are immutable in Python, meaning thelower()method returns a new string but does not change the original one.
- The loop goes through each element in
-
The
print(x):- After the loop completes, the list
xis still unchanged becauselower()was applied to each string but its result was not stored back inx.

Thus, the list x remains as ['XX', 'YY'].
