Break a number to its digits

n = int(input("n = "))
nInitial = n
nDigits = 0
for i in range(10):
    if n / (10**i) < 1:
        nDigits = i
        break
print("nDigits = " + str(nDigits))
digits = list()
for i in range(nDigits-1, -1, -1):
    digit = n // (10**i)
    n = n - digit * (10**i)
    digits.append(digit)
print(digits)
