Factorial number pythonClosed

Question

Hello, 

hi don't understand why this code doesn't give me the factorial number. 

somma = 0
i = 1
num = getInteger("Inserisci un numero e ti dirò il fattoriale: ")

if num == 1:
    print("Il fattoriale è 1 ")
else:
    while i < num:
        somma = i * num
    print("Il risultato è: ", somma)

Why do you not reduce 'num'  in the "while" cycle?

Just declare somma do not initialize it as zero.  "I" is always one.  You have a while statement that checks against a static variable.  Get rid of the while and calculate it directly as previously stated.  If "I" was an array, such as 1,3,5,7,9, then a while would be applicable, but it is not an array, it is static.
