Using python permutations function on a list

from itertools import permutations
a=permutations([1,2,3,4],2) 
for i in a: 
   print(i)

Using Python Permutations function on a String

from itertools import permutations 
string="SOFT"
a=permutations(string) 
for i in list(a): 
   # join all the letters of the list to make a string 
   print("".join(i))

all permutations python

import itertools

python all permutations of a string

>>> from itertools import permutations
>>> perms = [''.join(p) for p in permutations('stack')]
>>> perms

Permutation in python

from itertools import permutations
from itertools import combinations

for i in p:
    print(i)
c = combinations([1,2,3],2)
for j in c:
