Which of the following loops is not supported in Python?forwhiledo-whileNone of the above

To determine which of the given loops is not supported in Python, let's analyze each option:

1. for Loop: Python supports the for loop, which is used to iterate over a sequence (like a list, tuple, or string).

2. while Loop: Python also supports the while loop, which repeatedly executes a block of code as long as a given condition is true.

3. do-while Loop: Python does not have a built-in do-while loop structure. Although similar functionality can be achieved with a while loop, the specific do-while loop construct (which executes the loop body at least once before checking the condition) is not natively supported in Python.

4. None of the above: This choice implies that all loops mentioned are supported in Python, but since the do-while loop is not, this option cannot be correct.

Final Answer

The loop that is not supported in Python is the do-while loop.
