Python: Generates all possible permutations of n different objects
Python Itertools: Exercise-15 with Solution
Write a Python program to generate all possible permutations of n different objects.
Sample Solution:
Python Code:
import itertools
def permutations_all(l):
for values in itertools.permutations(l):
print(values)
permutations_all([1])
print("\n")
permutations_all([1,2])
print("\n")
permutations_all([1,2,3])
Sample Output:
(1,) (1, 2) (2, 1) (1, 2, 3) (1, 3, 2) (2, 1, 3) (2, 3, 1) (3, 1, 2) (3, 2, 1)

Python: Tips of the Day
Inverts a dictionary with non-unique hashable values:
Example:
def tips_collect_dictionary(obj): inv_obj = {} for key, value in obj.items(): inv_obj.setdefault(value, list()).append(key) return inv_obj ages = { "Owen": 25, "Jhon": 25, "Pepe": 15, } print(tips_collect_dictionary(ages))
Output:
{25: ['Owen', 'Jhon'], 15: ['Pepe']}
