Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.
Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is
Syntax: x = lambda arguments : expression
Now i will show you some python lambda function examples:

In this post, we will be talking about how Python likes to deal with “list-like objects”. We will be diving into some quirks of Python that might seem a bit weird and, in the end, we will hopefully teach you how to build something that could actually be useful while avoiding common mistakes.
Let’s start with this snippet.
class FakeList: def __getitem__(self, index): if index == 0: return "zero" elif index == 1: return "one" elif index == 2: return "two" elif index == 3: return "three" elif index == 4: return "four" elif index == 5: return "five" elif index == 6: return "six" else: raise IndexError(index) f = FakeList()
A lot of people will be familiar with this:
f ## <<< 'three'
__getitem__is the method you override if you want your instances to respond to the square bracket notation. Essentially

Python Programming language makes everything easier and straightforward. Effective use of its built-in libraries can save a lot of time and help with faster submissions while doing Competitive Programming. Below are few such useful tricks that every Pythonist should have at their fingertips:
