generates all possible combinations of 5 digit code using python

def comb(L):
for i in range(3):
for j in range(3):
for k in range(3):
# check if the indexes are not
# same
if (i!=j and j!=k and i!=k):
print(L[i], L[j], L[k])
# Driver Code
comb([1, 2, 3])

or another way to do this 

from itertools import permutations

# Get all combination of [1, 2, 3]
# of length 3
comb = permutations([1, 2, 3], 3)
for i in comb:
print(i)
