Find factorial using function in python
Web2 days ago · So there are a few things wrong with your answer. Firstly, you are resetting total to 0 in your while loop. Secondly, you are returning total in your while loop.. This means you are essentially only getting the first result of k=5 assuming n=6, k=5.. Thirdly, you are cutting the results of with while k >= 2, discounting k=1 and k=0.These 2 values should …
