python program to find factorial of a number
in this tutorial, we will learn python program to find factorial of a number without recursion.the user will give input as a number and program will give an output as the factorial of that number.
what is factorial
the factorial of a number is denoted by n! , it is the product of all positive integers less than or equal to n. For example,
the factorial of 5 is
5!=5*4*3*2*1=120
the factorial of 6 is
6*5*4*3*2*1=720
Note Factorial of 1 is 1 and facorial of 0 is also 1
python program to find factorial of a number
'''python program to find factorial of a number''' ''' input''' n=int(input("input number:")) f=1 '''factorial'' while(n>0): f=f*n n=n1 '''print''' print("Factorial of given number is: ") print(f)
logic to find python program to find factorial of a number

 user input will store in variable n.
 variable f will initialize with
 a loop will execute and calculate the factorial and sore in variable f
 loop will terminate when the value of n is zero
 print the output
Example 1 input number 5 Factorial of given number is: 120 Example 2 input number 6 Factorial of given number is: 720 Example 3 input number 4 Factorial of given number is: 24 Example 4 input number 0 Factorial of given number is: 1
