Does not require any prerequisites

Installation

1. Clone the repo

git clone https://github.com/TahsinCr/python-linqex.git

2. Install PIP packages

pip install linqex

Usage

Let's have different customers. Let's choose the male ones among these customers. For this:

from linqex.linq import Enumerable
customersList = [
    {'name' : 'Jonh', 'age' : 25, 'gender': 'male'},
    {'name' : 'Emma', 'age' : 44, 'gender': 'female'},
    {'name' : 'Steve', 'age' : 17, 'gender': 'male'}
]

customersEnumerable = Enumerable(customersList)

# to select only male ones:
customersMaleEnumerable = customersEnumerable.Where(lambda key, value: value['gender'] == 'male')

for customer in customersMaleEnumerable.ToList:
    print(customer)

Output

{'name' : 'Jonh', 'age' : 25, 'gender': 'male'}
{'name' : 'Steve', 'age' : 17, 'gender': 'male'}

Let's develop the example we wrote above a bit further:

from typing import Literal
from linqex.linq import Enumerable

MALE = "MALE"
FEMALE = "FEMALE"

class Customer:
    def __init__(self, id:int, name:str, age:int, gender:Literal["MALE","FEMALE"]):
        self.id = id
        self.name = name
        self.age = age
        self.gender = gender


customerList = [
    Customer(1, "Ava", 32, MALE),
    Customer(2, "Alex", 19, MALE),
    Customer(3, "Amelia", 22, FEMALE),
    Customer(4, "Arnold", 43, MALE),
    Customer(5, "Eric", 55, MALE),
    Customer(6, "Lily", 12, FEMALE),
    Customer(7, "Jessia", 32, MALE),
    Customer(8, "William", 19, MALE),
    Customer(9, "Emily", 22, FEMALE),
    Customer(10, "Mateo", 43, MALE),
    Customer(11, "Antony", 55, MALE),
    Customer(12, "Mia", 12, FEMALE)
]

customerEnumerable = Enumerable.List(customerList)

# to select only male ones:
customersMaleEnumerable = customerEnumerable.Where(lambda customer: customer.gender == MALE)

for customer in customersMaleEnumerable.ToList:
    print(customer.__dict__)

Output

{'id': 1, 'name': 'Ava', 'age': 32, 'gender': 'MALE'}
{'id': 2, 'name': 'Alex', 'age': 19, 'gender': 'MALE'}
{'id': 4, 'name': 'Arnold', 'age': 43, 'gender': 'MALE'}
{'id': 5, 'name': 'Eric', 'age': 55, 'gender': 'MALE'}
{'id': 7, 'name': 'Jessia', 'age': 32, 'gender': 'MALE'}
{'id': 8, 'name': 'William', 'age': 19, 'gender': 'MALE'}
{'id': 10, 'name': 'Mateo', 'age': 43, 'gender': 'MALE'}
{'id': 11, 'name': 'Antony', 'age': 55, 'gender': 'MALE'}
