find factorial using range function code example
Example 1: factorial python for loop
'''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)
Example 2: factorial in python using for loop
num = int(input('enter a number'))
factorial = 1
if num < 0:
print("Sorry, factorial does not exist for negative numbers")
elif num == 0:
print("The factorial of 0 is 1")
else:
for i in range(1,num + 1):
factorial = factorial*i
print("The factorial of",num,"is",factorial)
