1、首先安装urllib库，具体方法为 开始-运行-输入cmd 打开窗口提示符。输入命令pip urllib
3、接下来用input代码和用户交互，让用户输入关键词，具体代码如下：c = input("请输入关键词：")
5、接下来进行请求的发送，具体代码如下：url 屏顿幂垂= "https://www.baidu.com/sugrec?pre租涫疼迟=1&p=3&ie=utf-8&json=1&prod=pc&from=pc_web&sugsid=1445,21121,30790,30908,30823&wd="+ c +"&req=2&csor=2&pwd=fu%27zhuang&cb=jQuery110205928031753090219_1583222582808&_=1583222582819"res = urllib.request.urlopen(url)
7、经过以上代码，数据已经被全部提取出来，下面我们用正则单独提取有用数据，具体代码如下：pat = re.compile(r'","q":"(.*?)"},{"type')resc = re.findall(pat,data)
9、整体代码总结和运行效果：import urllib.requestimport urllib.parseimport rec = input("请输入关键词：")c = urllib.parse.quote(c,encoding="utf8")url = "https://www.baidu.com/sugrec?pre=1&p=3&ie=utf-8&json=1&prod=pc&from=pc_web&sugsid=1445,21121,30790,30908,30823&wd="+ c +"&req=2&csor=2&pwd=fu%27zhuang&cb=jQuery110205928031753090219_1583222582808&_=1583222582819"res = urllib.request.urlopen(url)data = res.read().decode("utf8")pat = re.compile(r'","q":"(.*?)"},{"type')resc = re.findall(pat,data)for i in resc: print(i)
