Practice: Factorials with While Loops
Find the factorial of a number using a
A factorial of a whole number is that number multiplied by every whole number between itself and 1. For example, 6 factorial (written “6!”) equals 6 x 5 x 4 x 3 x 2 x 1 = 720. So 6! = 720.
We can write a
while loop to take any given number and figure out what its factorial is.
number is 6, your code should compute and print the
# number to find the factorial of number = 6 # start with our product equal to one product = 1 # track the current number being multiplied current = 1 # write your while loop here # multiply the product so far by the current number # increment current with each iteration until it reaches number # print the factorial of number print(product)
Practice: Factorials with For Loops
Now use a
for loop to find the factorial!
It will now be great practice for you to try to revise the code you wrote above to find the factorial of a number, but this time, using a
for loop. Try it in the code editor below!
# number to find the factorial of number = 6 # start with our product equal to one product = 1 # write your for loop here # print the factorial of number print(product)
