Introduction
Python is a high-level, interpreted programming language known for its simplicity and readability. It is widely used for web development, data analysis, artificial intelligence, and many other applications. Python's syntax is designed to be intuitive, making it easy to learn and use.
Setting Up Python
Before you can start coding in Python, you need to install the Python interpreter. You can download the latest version of Python from the official website: Python.org. Follow the installation instructions for your operating system.
Basic Syntax
Python uses indentation to define the scope of code blocks. Here's a simple example:
print("Hello, World!")
In this example, the print function is used to display the text "Hello, World!" on the console.
Variables and Data Types
Variables are used to store data values. In Python, you can declare a variable by simply assigning a value to it:
age = 25
name = "Alice"
Python has several built-in data types, including integers, floating-point numbers, strings, and booleans.
Control Structures
Control structures allow you to control the flow of execution in your program. Here are some common control structures in Python:
- If-else statements: Used to make decisions based on conditions.
- For loops: Used to iterate over a sequence of values.
- While loops: Used to repeat a block of code until a certain condition is met.
Functions
Functions are reusable blocks of code that perform a specific task. You can define your own functions or use built-in functions provided by the Python standard library.
Error Handling
Error handling is an essential part of programming. Python provides several ways to handle errors, such as try-except blocks.
