Python: All possible combinations of the elements of a given list, use itertools module
Python Itertools: Exercise-35 with Solution
Write a Python program to get all possible combinations of the elements of a given list using the itertools module.
Sample Solution:
Python Code:
import itertools
def combinations_list(list1):
temp = []
for i in range(0,len(list1)+1):
temp.append(list(itertools.combinations(list1,i)))
return temp
colors = ['orange', 'red', 'green', 'blue']
print("Original list:")
print(colors)
print("\nAll possible combinations of the said list’s elements:")
print(combinations_list(colors))
Sample Output:
Original list: ['orange', 'red', 'green', 'blue'] All possible combinations of the said list’s elements: [[()], [('orange',), ('red',), ('green',), ('blue',)], [('orange', 'red'), ('orange', 'green'), ('orange', 'blue'), ('red', 'green'), ('red', 'blue'), ('green', 'blue')], [('orange', 'red', 'green'), ('orange', 'red', 'blue'), ('orange', 'green', 'blue'), ('red', 'green', 'blue')], [('orange', 'red', 'green', 'blue')]]

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']}
