Question
What is the output of the following program?c = ['code', 'tantra']for t in c: t.upper()print(c)Options['CODE' , 'TANTRA']TANTRA['code', 'tantra']CODE
Solution
The output of the program will be ['code', 'tantra'].
Here's why:
- The program starts by defining a list
cwith two strings: 'code' and 'tantra'. - Then it enters a for loop where it goes through each element
tin the listc. - For each element, it applies the
upper()method, which converts all the characters in a string to uppercase. However, this doesn't change the original string because strings in Python are immutable, which means they can't be changed after they are created. Theupper()method returns a new string and doesn't modify the original one. - After the loop, the program prints the list
c. Since none of the strings in the list were modified in the loop, the output will be the original list: ['code', 'tantra'].
