1. Introduction to Python
Python is a versatile, high-level programming language that is widely used in various domains such as web development, data analysis, machine learning, and more. It is known for its simplicity, readability, and vast community support.
2. Python Installation
To get started with Python, you need to install it on your machine. Here are the steps to install Python:
- Go to the official Python website (https://www.python.org/) and download the latest version of Python.
- Run the installer and follow the installation wizard.
- Make sure to check the option to add Python to your PATH environment variable.
- Verify the installation by opening a command prompt and typing
python --version
.
3. Variables and Data Types
In Python, variables are used to store data. Here are some of the commonly used data types in Python:
- Integer:
age = 25
- Float:
height = 1.75
- String:
name = "John"
- Boolean:
is_student = True
4. Operators and Expressions
Python provides a wide range of operators to perform operations on variables and values. Here are some examples:
- Arithmetic Operators:
+
,-
,*
,/
- Comparison Operators:
==
,!=
,>
,<
- Logical Operators:
and
,or
,not
5. Control Flow
Control flow statements allow you to control the execution of code based on certain conditions. Here are some commonly used control flow statements:
- If-else Statement:
-
Loops:
- For Loop:
- While Loop:
6. Functions
Functions are reusable blocks of code that perform a specific task. Here’s an example of defining and calling a function in Python:
7. Data Structures
Python provides various data structures to store and manipulate data efficiently. Let’s take a look at some commonly used data structures:
- Lists:
[1, 2, 3]
- Tuples:
(1, 2, 3)
- Dictionaries:
{"name": "John", "age": 25}
- Sets:
{1, 2, 3}
8. File Handling
Python allows you to read from and write to files using file handling operations. Here’s an example:
- Reading from a File:
- Writing to a File:
9. Exception Handling
Exception handling allows you to handle and recover from errors or exceptional situations in your code. Here’s an example:
10. Modules and Packages
Modules and packages help in organizing and reusing code. Here’s an example of importing and using a module in Python:
11. Object-Oriented Programming
Python supports object-oriented programming principles. Here’s an example of defining a class and creating objects:
12. Regular Expressions
Regular expressions allow you to match and manipulate strings based on specific patterns. Here’s an example:
13. Database Connectivity
Python provides libraries to connect with databases like MySQL, PostgreSQL, and SQLite. Here’s an example of connecting to a MySQL database:
14. Web Scraping
Python is a powerful tool for web scraping. Here’s an example using the BeautifulSoup library:
