Question
What is the output of the following?ct = ['code', 'tantra']for x in ct: x.upper()print(ct)Options[‘CODE’, ‘TANTRA’].[None, None].Unexpected[‘code’, ‘tantra’].
Solution
The output of the given code will be ['code', 'tantra'].
Here's the step by step explanation:
- We have a list
ctwith two elements: 'code' and 'tantra'. - Then we have a for loop that goes through each element in the list.
- For each element, it calls the
upper()method, which converts all the characters of the string to uppercase. However, this doesn't change the original string because strings in Python are immutable, which means they cannot be changed after they are created. Theupper()method returns a new string. - Since we are not storing the result of
x.upper()anywhere, the original listctremains unchanged. - Finally, when we print
ct, it outputs the original list: ['code', 'tantra'].
