Introduction

pyfuncol is a Python functional collections library. It extends collections built-in types with useful methods to write functional Python code. It uses Forbidden Fruit under the hood.

pyfuncol provides:

• Standard “eager” methods, such as map, flat_map, group_by, etc.

• Parallel methods, such as par_map, par_flat_map, etc.

• Pure methods that leverage memoization to improve performance, such as pure_map, pure_flat_map, etc.

• Lazy methods that return iterators and never materialize results, such as lazy_map, lazy_flat_map, etc.

pyfuncol can also be used without forbiddenfruit.
