producing numbers out of a list

[bowlofred]

What about if i want to product numbers out of the same digits without repition ?
I mean i don't want to product numbers like 1111, 1114, 1115 etc. I want to use a digit only once in a number.

Then you want "permutations". You need to make sure you only give it each digit one time or it will repeat it.

from itertools import permutations

digits = "1457"

for number_str in permutations(digits, 4):
    number = int("".join(number_str))
    print(number)

Output:
1457
1475
1547
1574
1745
1754
4157
4175
...
