Factorial if you don't know is for ex. Say 5!=54321=120 I wrote this code:

n=1 k=input("Enter factorial here: ")

While n>=k:

print(n)

n=n+1

........................ Output comes say if k=3

3

2

1

I want to know How can I get 321 using while loop.

So I took a beginner Python class and I'm already lost.

We are supposed to build a calculator using for/while -loop. The program is supposed to ask a number and if the choice is "0" - the program will close. If the input is "1", the program will ask another number and will then get the factorial value of that number.

I can barely understand what I'm supposed to be doing and I got my code working as long as the input value is 0-3. After that it doesn't work. This is the given example:

• 0! = 1

• 1! = 0!*1 = 1

• 2! = 1!*2 = 2

• 3! = 2!*3 = 6

• 4! = 3!*4 = 24

• 5! = 4!*5 = 120

• 6! = 5!*6 = 720

Edit:

Did all the changes and the code looks like this now! Still not passable tho. D:

Here are the requirements in case I have misunderstood something:

"You need to have variables "factorial" and " counter" they both have int values of 1!"

"While -loop must repeat until counter is less than or equal to num"

"You need to assign a variable called "factorial2" from factorial * counter"

"counter value +1 after every loop"

choice = input('0 - closes the program, 1 - get factorial value: ')

while True:
    
    if choice == '1':
        num = input('Give a number: ')
        num = int(num)
        factorial = 1
        
        for i in range(1, num + 1):
            factorial = factorial * i

        print(str(num) + '! = ',  factorial)
        
    elif choice == '0':
        print('Program will be closed!')
        break
    
    else:
        print('Please give either 0 or 1!')
        choice = input('0 - closes the program, 1 - get factorial value: ')
        continue

I'm so lost. This is literally my third assignment and all our materials for this assignment teach us is the basic functions of while/for -loop. :( Feeling so disheartened at the moment.

EDIT: Made some progress. It's still not passable but it's closer. I got a tip that I need to assign factorial2 variable from factorial * counter But... I don't get how can I do this. This code does what is asked, but it's not done the right way I guess...
