It returns True when it should return False. Many thanks for your help.
The function exits once a return statement is reached. That means on the first iteration when n = 2, either True or False will be returned. Move the return True part out of the loop.
Many thanks. It was an indentation problem.
Can you paste the rectified code that worked for you ?
