Using python

Write a Python function called sgm that requests a positive integer n and returns the series geometric mean of the numbers 1,2,3, . . . n. For example sgm(5) =

(5 x 4 x 3 x 2 x 1)^1/5 = (120) ^1/5 = 2.605 . Write the program so that a user is requested for a positive integer and program prints the series geometric mean of the integer.

Example execution:

Enter number: 5

series geometric mean of 5 = 2.605
