Correct option is B
The given Python code first stores the string "Python Programming" in the variable S. Using the split() method without any argument splits the string at whitespace, resulting in a list of words: ['Python', 'Programming']. Then, the join() method combines these list elements back into a single string using a comma (,) as the separator. Hence, the final output printed is Python,Programming, which corresponds to option (b).
Important Key Points:
- split() Function: When used without arguments, split() divides a string based on spaces.
- Intermediate List Formed: L = ['Python', 'Programming']
- join() Function: ','.join(L) joins list elements using a comma as a separator.
- Separator Behavior: The separator appears only between elements, not at the beginning or end.
- Final Value of S: S = "Python,Programming"
- Printed Output: The print(S) statement displays the final joined string.
Knowledge Booster:
- Why option (a) is incorrect?
This would be the original string, but the code modifies it using split() and join(). - Why option (c) is incorrect?
join() does not add separators at the beginning or end. - Why option (d) is incorrect?
Extra commas before and after elements are not added by join(). - Example: '-'.join(['A', 'B', 'C']) # Output: A-B-C
