Learn about variable scope in Python. Variable scope simply defines the scope of variables i.e. where can we access or use the variables based on their scopes or based on the location where they are defined.
Learn about variable scope in Python. Variable scope simply defines the scope of variables i.e. where can we access or use the variables based on their scopes or based on the location where they are defined. We have following variable scopes: L == Local E == Enclosing G == Global B == Built-in
When we create a variable inside a function, that variable is called local variable of that function which is only accessible within that function. When we create a nested function inside a function, all the variables that are defined inside the outer function i.e. all the variables that are defined outside the inner or nested function, those variables will be the enclosing variables of inner function. When we create a variable outside a function, that variable is called global function which is accessible anywhere in the program OR which is accessible globally. Built-in variables are those which are pre-defined in the Python itself like print, max, min, count, global, nonlocal etc.
In this tutorial, you’re going to learn a variety of Python tricks that you can use to write your Python code in a more readable and efficient way like a pro.
Today you're going to learn how to use Python programming in a way that can ultimately save a lot of space on your drive by removing all the duplicates. We gonna use Python OS remove( ) method to remove the duplicates on our drive. Well, that's simple you just call remove ( ) with a parameter of the name of the file you wanna remove done.
In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.
Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc.. You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like __init__, __call__, __str__ etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).
The OS module is a python module that provides the interface for interacting with the underlying operating system that Python is running.
