Write a Python program to generate all sublists of a list.

 

Sample Solution

Python Code:

from itertools import combinations
def sub_lists(my_list):
	subs = []
	for i in range(0, len(my_list)+1):
	  temp = [list(x) for x in combinations(my_list, i)]
	  if len(temp)>0:
	    subs.extend(temp)
	return subs


l1 = [10, 20, 30, 40]
l2 = ['X', 'Y', 'Z']
print("Original list:")
print(l1)
print("S")
print(sub_lists(l1))
print("Sublists of the said list:")
print(sub_lists(l1))
print("nOriginal list:")
print(l2)
print("Sublists of the said list:")
print(sub_lists(l2))

Sample Output:

Original list:
[10, 20, 30, 40]
S
[[], [10], [20], [30], [40], [10, 20], [10, 30], [10, 40], [20, 30], [20, 40], [30, 40], [10, 20, 30], [10, 20, 40], [10, 30, 40], [20, 30, 40], [10, 20, 30, 40]]
Sublists of the said list:
[[], [10], [20], [30], [40], [10, 20], [10, 30], [10, 40], [20, 30], [20, 40], [30, 40], [10, 20, 30], [10, 20, 40], [10, 30, 40], [20, 30, 40], [10, 20, 30, 40]]

Original list:
['X', 'Y', 'Z']
Sublists of the said list:
[[], ['X'], ['Y'], ['Z'], ['X', 'Y'], ['X', 'Z'], ['Y', 'Z'], ['X', 'Y', 'Z']]
