powerset-generator 0.1.3

Generate the power set of a collection

Python Power set generator

Documentation PyPi

---

Installation

pip install powerset-generator

Example

import powerset_generator

for e in powerset_generator.subsets(["one", "two", "three", "three"]):
    print(e)

produces

set()
{'one'}
{'three'}
{'two'}
{'one', 'three'}
{'one', 'two'}
{'three', 'two'}
{'one', 'three', 'two'}

Note that the empty set, set() is included in the output and that the function treats the duplicated input element "three" as if it appeared only once. This is correct behavior the mathematical notion of power set.

See the more complete (perhaps excessively so) documentation for more details.

The code for the subsets() function is derived heavily from Allen Downey's Stack Overflow answer.
