permutation and combination using python without using library code example

Example 1: permutation and combination code in python

# A Python program to print all  
# combinations of a given length  
from itertools import combinations  
  
# Get all combinations of [1, 2, 3]  
# and length 2  
comb = combinations([1, 2, 3], 2)  
  
# Print the obtained combinations  
for i in list(comb):  
    print (i)

Example 2: permutation and combination code in python

# A Python program to print all  
# permutations of given length  
from itertools import permutations  
  
# Get all permutations of length 2  
# and length 2  
perm = permutations([1, 2, 3], 2)  
  
# Print the obtained permutations  
for i in list(perm):  
    print (i)
