Introduction to Python Programming Course

Python Self-Learning Secrets

This course covers the core foundational concepts of Python. It is recommended to practice each knowledge point with code to deepen understanding through repeated exercises. The key to learning programming is continuous practice. Wishing you a fruitful journey in learning Python!

Python Programming Introduction: From Zero to Your First Program

1. Introduction to Python

Python is a high-level, interpreted, general-purpose programming language, released by Guido van Rossum in 1991. It is known for its concise syntax and powerful features, including:

• High readability: close to natural language expression
• Cross-platform: supports Windows/macOS/Linux
• Rich libraries: over 200,000 third-party libraries (in fields such as data analysis, artificial intelligence, etc.)
• Application areas: Web development, automation scripts, data analysis, artificial intelligence, etc.

2. Setting Up the Development Environment

1. Install Python: Visit the official website: python.org to download the latest version (recommended 3.10+), and check “Add Python to PATH” during installation.
2. Select Development Tools

Recommended for beginners: IDLE (comes with Python) Advanced options: VS Code/PyCharm

3. Your First Program: Open IDLE, input

print("Hello, World!")

Press F5 to run, and the console will display the output result.

3. Basic Syntax

1. Variables and Data Types

x = 5

2. Basic Operations

y = x + 10

3. Input and Output

name = input("Enter your name:")

4. Data Structures

1. Lists

my_list = [1, 2, 3]

2. Tuples

my_tuple = (1, 2, 3)

3. Dictionaries

my_dict = {'key': 'value'}

5. Control Flow

1. Conditional Statements

if x > 0:

2. Loop Structures

For Loop

for i in range(5):

While Loop

while x < 10:

6. Basics of Functions

1. Defining Functions

def my_function():

2. Calling Functions

my_function()

7. File Operations

1. Writing to Files

with open('file.txt', 'w') as f:

2. Reading from Files

with open('file.txt', 'r') as f:

8. Practical Exercise: Temperature Converter

def celsius_to_fahrenheit(celsius):

9. Learning Suggestions

1. Practice hands-on, try modifying example code.
2. Gradually challenge small projects: calculator, simple address book, etc.
