以下是几个简单的Python爬虫代码示例： ### 爬取百度页面并打印页面信息 ```python import requests response = requests.get("http://www.baidu.com") response.encoding = response.apparent_encoding print("状态码:"+ str( response.status_code )) print(response.text) ``` ### Requests常用方法之get方法实例 ```python import requests response = requests.get("http://httpbin.org/get") print( response.status_code ) print( response.text ) ``` ### Requests常用方法之post方法实例 ```python import requests response = requests.post("http://httpbin.org/post") print( response.status_code ) print( response.text ) ``` ### put方法实例 ```python import requests response = requests.put("http://httpbin.org/put") print( response.status_code ) print( response.text ) ``` ### 爬取一个html并保存 ```python import requests url = "http://www.baidu.com" response = requests.get( url ) response.encoding = "utf-8" print("\nr的类型" + str( type(response) )) print("\n状态码是:" + str( response.status_code )) print("\n头部信息:" + str( response.headers )) print( "\n响应内容:" ) print( response.text ) file = open("D:\\爬虫\\baidu.html","w",encoding="utf-8") file.write( response.text ) file.close() ``` ### 爬取图片并保存到本地 ```python import requests response = requests.get("https://www.baidu.com/img/baidu_jgylogo3.gif") file = open("D:\\爬虫\\baidu_logo.gif","wb") file.write(response.content) file.close() ``` 以上代码示例来自引用内容，通过这些示例可以了解Python爬虫常见任务的基础实现，根据具体需求还可进一步扩展和优化 [^1][^2][^3][^4]。
