# 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.
## Available methods
| methods | action |
|----------------------------| -------------------------------------------------- |
| count() | gets the number of total elements in the list |
| json() | jsonifies the list |
| find(callaback: Callable) | returns the first item that match with the callback |
| where(callback: Callable) | returns a new collection that meets the callback |
| item(element) | transforms each of the elements of the list when it is iterated over it |
| first() | gets the first item of the list |
| append(element) | add a new element to the list |
| items() | retrieves the collection list |
| random() | retrieves a random item from the collection |
| get(index:int) | retrieves an element according to the given index |
