Getting "NameError: name 'requests' is not defined" after already installing requests (using JuypterLab)

Question

我已经使用 'pip install requests' 安装了请求，但我什么也没得到。

我正在按照基本 tutorial 中给出的示例进行操作，并在 code:

上继续获取此 error

from bs4 import BeautifulSoup
page = requests.get('https://forecast.weather.gov/MapClick.php?lat=47.19044000000008&lon=-122.29563999999999#.Xq3cLZl7lPY')
soup = BeautifulSoup(page.content, 'html-parser')
print(soup)

和 error:

---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
<ipython-input-1-90e58007c1ee> in <module>
      1 from bs4 import BeautifulSoup
----> 2 page = requests.get('https://forecast.weather.gov/MapClick.php?lat=47.19044000000008&lon=-122.29563999999999#.Xq3cLZl7lPY')
      3 soup = BeautifulSoup(page.content, 'html-parser')
      4 print(soup)

NameError: name 'requests' is not defined

Answer 1

我认为，你需要import requests。你可以试试：

from bs4 import BeautifulSoup
import requests
page = requests.get('https://forecast.weather.gov/MapClick.php?lat=47.19044000000008&lon=-122.29563999999999#.Xq3cLZl7lPY')
soup = BeautifulSoup(page.text, 'lxml')
print(soup)
