find factorial of a number using loops in python code example
Example 1: python calculate factorial
def factorial(n):
fact = 1
for num in range(2, n + 1):
fact = fact * num
return(fact)
Example 2: factorial python for loop
#Factorial
'''factorial n! - n* n-1*n-2..1'''
def fac_iterative_method(n):
fac = 1
for i in range(n):
fac = (fac * (i+1))
print('fac of',i+1,'=',fac)
number = int(input('enter the number'))
fac_iterative_method(number)
