PythonLibrary是指一组用Python编写的可重用代码模块,旨在方便Python开发人员编写应用程序、脚本或其他工具。Python库通常被称为模块或包。

Python库提供了许多功能,例如文件I/O、网络编程、科学计算、数据处理和图形用户界面等。它们可以节省程序员大量的时间和精力,并可以在开源项目中使用。

下面是一些简单的示例:

1. datetime模块:这个模块提供了日期和时间处理的函数和类。例如,可以使用datetime.datetime.now()函数获取当前日期和时间。

python
import datetime
now = datetime.datetime.now()
print(now)


输出:

2023-03-27 10:56:52.637775


2. requests库:这个库使得HTTP请求变得容易,可以轻松地发送HTTP请求并处理响应。例如,可以使用requests.get()方法获取网页的内容。

python
import requests
response = requests.get('https://www.google.com/')
print(response.content)


输出:
