What is Python?
Python is a high-level, interpreted programming language. It was created by Guido van Rossum in 1991 and is now one of the most popular programming languages in the world. Python is an interpreted language, meaning that it can be written and executed without the need for a compiler. This makes it ideal for beginners who want to learn how to code quickly and easily.

It is also a great language for experienced developers who want to create powerful applications.
Getting Started with Python
Before you can start writing code in Python, you need to install the language on your computer. Python is available for free on the official website. Once you have installed Python, you can start writing code in any text editor.
The first step in writing code in Python is to create a file. This file will contain the code that you write. To create a file, open a text editor and save the file with the extension .py. This will tell the computer that the file contains Python code.
Once you have created the file, you can start writing code. Python is an interpreted language, meaning that it can be written and executed without the need for a compiler. This makes it ideal for beginners who want to learn how to code quickly and easily.
Variables
Variables are used to store data in a program. In Python, variables are declared using the keyword “var” followed by the name of the variable. For example, to declare a variable called “name”, you would write:
“`
var name
“`
Once a variable is declared, you can assign a value to it. For example, to assign the value “John” to the variable “name”, you would write:
“`
name = “John”
“`
Variables can be used to store any type of data, including numbers, strings, lists, and more.
Data Types
Python has a number of built-in data types. These data types are used to store different types of data in a program. The most common data types are integers, floats, strings, and booleans.
Integers are whole numbers, such as 1, 2, 3, etc. Floats are numbers with decimal points, such as 1.5, 2.3, etc. Strings are sequences of characters, such as “Hello”, “Goodbye”, etc. Booleans are values that can be either True or False.
Functions
Functions are used to perform specific tasks in a program. In Python, functions are declared using the keyword “def” followed by the name of the function. For example, to declare a function called “greet”, you would write:
“`
def greet():
“`
Once a function is declared, you can write code inside the function. This code will be executed when the function is called. For example, to print the string “Hello World” when the function “greet” is called, you would write:
“`
def greet():
print(“Hello World”)
“`
Functions can also accept parameters, which are values that are passed to the function when it is called. For example, to print the string “Hello [name]” when the function “greet” is called, you would write:
“`
def greet(name):
print(“Hello ” + name)
“`
Classes
Classes are used to create objects in Python. Objects are used to store data and perform tasks. In Python, classes are declared using the keyword “class” followed by the name of the class. For example, to declare a class called “Person”, you would write:
“`
class Person:
“`
Once a class is declared, you can define attributes and methods inside the class. Attributes are used to store data, and methods are used to perform tasks. For example, to define an attribute called “name” and a method called “greet” in the class “Person”, you would write:
“`
class Person:
name = “”
def greet(self):
print(“Hello ” + self.name)
“`
Python Libraries and Frameworks
Python has a number of popular libraries and frameworks that can be used to create powerful applications. These libraries and frameworks make it easier to write code and create powerful applications. Some of the most popular Python libraries and frameworks are Django, Flask, and TensorFlow.
