How to check if a specific digit is in an integer

Question

I want to check if, for example, the digit \'2\' is in 4059304593. My aim is to then check if there are any of the digits 1-9 not in my integer. This is what I have tried:

Answer 1

L = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
j = 0
nL = [0, 0, 0, 0, 0, 0, 0, 0, 0]
n = 1004 #number
while n:
    i = n%10
    nL[i] = 1
    n //= 10

OUT

nL = [1, 1, 0, 0, 1, 0, 0, 0, 0, 0]

Explanation: if nL[i] is 1, then the i-th digit is in n
