Welcome to the Python Developer Tutorial! Whether you're new to Python or looking to deepen your understanding, this guide will help you get started.

Python 简介

Python is a high-level, interpreted programming language known for its simplicity and readability. It's widely used in web development, data analysis, artificial intelligence, and more.

Python 基础语法

变量和数据类型

In Python, you can declare variables without specifying their data type. Here are some common data types:

  • int: Integer
  • float: Floating-point number
  • str: String
  • bool: Boolean
age = 25
height = 5.9
name = "John Doe"
is_student = True

控制流

Python uses indentation to define blocks of code. Here are some basic control structures:

  • if-else statements
  • Loops (for and while)
if age > 18:
    print("You are an adult")
else:
    print("You are not an adult")

for i in range(5):
    print(i)

函数

Functions are blocks of reusable code. Here's an example of a simple function:

def greet(name):
    return f"Hello, {name}!"

print(greet("John Doe"))

模块和包

Python modules and packages are collections of functions and classes. You can import them into your scripts to use their functionality.

import math

print(math.sqrt(16))

异常处理

Exception handling is a way to manage errors in your code. Here's an example:

try:
    result = 10 / 0
except ZeroDivisionError:
    print("Cannot divide by zero")
