pin code

Question

can any body help me to write code using recursive function to print pin code. by giving the program pin length and the max number it will give you pin code. for example: when we give it length is 3 and the max number is 2. It will print:
111
112
121
122
211
212
221
222
thanks in advance

Answer 1

Python 3 has a function to do this actually.
from itertools import product
If we wanted to print out exactly what you wrote:
print(list(product([1,2], repeat=3)))
The list contains the numbers you wish to make permutations from, so the digits you want to make combinations from. The repeat flag specifies the length of the permutation. In this case, the length of your pin.

I'll leave it up to you how you want to set the values and all that.
