Python程序生成谷歌搜索url

了解了请求模块后，我尝试实现它

代码1:

import requests
search = str(input())
d={'q': search}
results = requests.get('https://google.com/search', params=d)
print(results.url)

Python

https://www.google.com/search?q=Python

import requests

search = str(input('Enter what you want to search:'))
user_input = input('Enter websearch, images, shopping, news, videos:')

if user_input == 1:
    d={'q': search}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 2:
    d={'q': search, 'tbm':'isch'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 3:
    d={'q': search, 'tbm':'shop'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 4:
    d={'q': search, 'tbm':'nws'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 5:
    d={'q': search, 'tbm':'vid'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

Enter what you want to search:Python
Enter websearch, images, shopping, news, videos:1

输出1:

import requests
search = str(input())
d={'q': search}
results = requests.get('https://google.com/search', params=d)
print(results.url)

Python

https://www.google.com/search?q=Python

import requests

search = str(input('Enter what you want to search:'))
user_input = input('Enter websearch, images, shopping, news, videos:')

if user_input == 1:
    d={'q': search}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 2:
    d={'q': search, 'tbm':'isch'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 3:
    d={'q': search, 'tbm':'shop'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 4:
    d={'q': search, 'tbm':'nws'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 5:
    d={'q': search, 'tbm':'vid'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

Enter what you want to search:Python
Enter websearch, images, shopping, news, videos:1

一切都很好，我复制了链接，它给出了正确的结果，但在临时修改代码时，我得到了一个错误（链接输出未生成）

代码2:

import requests
search = str(input())
d={'q': search}
results = requests.get('https://google.com/search', params=d)
print(results.url)

Python

https://www.google.com/search?q=Python

import requests

search = str(input('Enter what you want to search:'))
user_input = input('Enter websearch, images, shopping, news, videos:')

if user_input == 1:
    d={'q': search}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 2:
    d={'q': search, 'tbm':'isch'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 3:
    d={'q': search, 'tbm':'shop'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 4:
    d={'q': search, 'tbm':'nws'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

elif user_input == 5:
    d={'q': search, 'tbm':'vid'}
    results = requests.get('https://google.com/search', params=d)
    print(results.url)

Enter what you want to search:Python
Enter websearch, images, shopping, news, videos:1

输出2:

import requests
search = str(input())
d={'q': search}
results = requests.get('https://google.com/search', params=d)
print(results.url)

Python

https://www.google.com/search?q=Python

import requests

search = str(input('Enter what you want to search:'))
user_input = input('Enter websearch, images, shopping, news, videos:')

if user_input == 1:

    results = requests.get('https://google.com/search', params=d)
    print(results.url)

Enter what you want to search:Python
Enter websearch, images, shopping, news, videos:1

这就是我在没有链接的情况下得到的输出。我是Python编程新手。

input（）

返回一个字符串，因此当您检查

用户输入==1

时，实际上是在做

“1”==1

，Python认为这是

错误的。您应该尝试使用
int（）
将输入转换为整数

请注意，如果传递到
int（）
的内容无法转换为整数，则这将引发
ValueError
