I’m trying to create a program in python which generates all the possible combinations (non-repeating) for a given number
If the input is “123”, Output should be
123,132,213,231,312,321 12,13,21,23,31,32 1,2,3
My current code is
import itertools a=[1,2,3] for i in range(1,len(a)+1): print(list(itertools.combinations(a,i)))

You can use itertools.permutations
:
import itertools def permute_all(value): return [''.join(permutation) for i in range(len(value)) for permutation in itertools.permutations(value, i+1)] print(permute_all('123')) # Outputs ['1', '2', '3', '12', '13', '21', '23', '31', '32', '123', '132', '213', '231', '312', '321']
