To find the factorial of a number in Python, you can use a for loop to iterate over a range of numbers and compute the factorial of the given number. Here’s an example:

# define a function to compute the factorial of a number
def factorial(n):
# initialize the factorial to 1
fact = 1
# iterate over a range of numbers from 1 to the given number
for i in range(1, n+1):
# multiply the factorial by the current number
fact = fact * i
# return the factorial
return fact
# get the number from the user
num = int(input("Enter a number: "))
# compute and print the factorial of the given number
print(f"The factorial of {num} is {factorial(num)}")

This code defines a function called factorial() that takes a single argument n, which is the number for which we want to compute the factorial. Inside the function, we initialize a variable called fact to 1, which will hold the result of the factorial. Then, we use a for loop to iterate over the range of numbers from 1 to the given number n, and multiply the factorial by each number in the range. Finally, we return the factorial.

To use the factorial() function, we get the number from the user using the input() function, and then pass it to the factorial() function as an argument. The factorial() function returns the factorial of the given number, which we then print using the print() function.

Here’s an example of how this code would work:

Enter a number: 5
The factorial of 5 is 120

In this example, the user entered the number 5, so the factorial() function computed the factorial of 5, which is 120.
