pycollection 1.0.6

Collection iterator over classes

pycollection

pycollection is an amazing library that allows you to iterate through a list, but it returns a transformed item. It has a lot of methods to interact with the collection. It works similar than laravel collections.

Instalation

pip install pycollection

Basic usage

from pycollection import collection

class NumberCollection(Collection):

    def item(self, item):
        return Number(item)


class Number:

    def __init__(self, item):
        self._item = item

    def value(self):
        return self._item

    def squared(self):
        return self._item * self._item


numbers = NumberCollection([1,2,3,4,5])


for number in numbers:
    print(number.squared())

# output
# > 1
# > 4
# > 9
# > 16
# > 25

As you can see, it allows for an easy-to-read syntax for navigating between lists and their elements, since you can provide new functionality to both.
