我的谷歌搜索代码需要改进

Question

这是我的程序的一部分，您可以在其中输入一个命令（变量com），如果该命令包含google或search，它将执行google搜索。 是否有人可以帮助修复它，以便它也可以与包含谷歌的搜索一起工作（例如：“谷歌如何赚钱”）

if 'google' in com or 'search' in com:
    search=''
    foo=com.split()        
    for x in foo:
        if x!='google' and x!='search':
            search+='+'+x
    search=search[1:]
    print('googling:'+search)
    time.sleep(1)
    web.open('https://www.google.co.in/search?q='+search+'&oq='+search+'&aqs=chrome..69i57j69i60l2j69i61j69i60j69i61.306j0j9&s0ourceid=chrome&ie=UTF-8')

Answer 1

您正在从搜索请求中删除google或search的所有部分，无论它们位于com变量的何处

只需将其拆分为first:rest，这样您就可以持有命令（只有cmd的第一个单词）和请求（其余的cmd）：

com = 'google how google makes money'
url = 'https://www.google.com/search?q={query:s}'
pts = com.split()
cmd, qry = pts[0], ' '.join(pts[1:])

这就是：

print(cmd)
>>> 'google'
print(qry)
>>> 'how google makes money'

然后，您可以像往常一样执行查询。顺便说一下：您不需要提供完整的url，包括从浏览器复制的所有令牌：

import requests
from bs4 import BeautifulSoup

if cmd in ['google', 'search']:
    res = requests.get(url.format(query=qry))
    sup = BeautifulSoup(res.text, 'html.parser')

    res_root = sup.find('div', id='ires')
    for entry in res_root.find_all('h3'):
        print(entry.text)
