In mathematics, a power set of any set is a set that contains all the possible subsets of a given set along with an empty set. In other words, all subsets of a set is also known as a powerset. There can be a power set of lists, sets, strings, etc., in Python.
How does Python calculate Powerset?
- def get_subsets(fullset):
- listrep = list(fullset)
- subsets = []
- for i in range(2**len(listrep)):
- subset = []
- for k in range(len(listrep)):
- if i & 1<<k:
- subset. append(listrep[k])
How do you make a Powerset?
To generate the power set, observe how you create a subset : you go to each element one by one, and then either retain it or ignore it. Let this decision be indicated by a bit (1/0). Thus, to generate {1} , you will pick 1 and drop 2 (10).
