program to take input for a number calculate and display its factorial

Write a program to take input for a number calculate and display its factorial.

def fact(n):

f=1

i=1

while i<=n:

f=f*i

i=i+1

print("Factorial = ",f)

def main():

a=int(input("Enter any no "))

fact(a)

"""

if __name__=='__main__':

main()

"""

#or

#function calling

main()

Output:-

(1). Enter any no 5

Factorial = 120

(2). Enter any no 8

Factorial = 40320

(3). Enter any no 10

Factorial = 3628800
