Program Explanation

For Statement is used to execute the sequence of instruction repeatedly.

Range() method gives list of elements, here range() method gives list which has 1,2,3... to n. for statement executes the instructions iteratively and for takes the elements one by one as value of i in sequential manner.

so it multiplies with fact in every iteration, finally produces product of n natural numbers.
