我正在尝试从阳光基金会打开此 API 的 URL，并从 json 中的页面返回数据。这是我生成的代码，减去 myapikey 周围的括号。
import urllib.request.urlopen
import json
urllib.request.urlopen("https://sunlightlabs.github.io/congress/legislators?api_key='(myapikey)")
and im getting this error
我收到这个错误
Traceback (most recent call last):
File "<input>", line 1, in <module>
ImportError: No module named request.urlopen

我究竟做错了什么？我研究了https://docs.python.org/3/library/urllib.request.html仍然没有进展

You need to use from urllib.request import urlopen, also I suggest you use the withstatement while opening a connection.
您需要使用from urllib.request import urlopen，另外我建议您with在打开连接时使用该语句。
from urllib.request import urlopen
with urlopen("https://sunlightlabs.github.io/congress/legislators?api_key='(myapikey)") as conn:
# dosomething

In Python 3 You can implement that this way:
在 Python 3 中，您可以通过以下方式实现：
import urllib.request
u = urllib.request.urlopen("xxxx")#The url you want to open
Pay attention:Some IDE can import urllib(Spyder) directly, while some need to import urllib.request(PyCharm).
注意：有的IDE可以import urllib直接（Spyder），有的需要import urllib.request（PyCharm）。
That's because you sometimes need to explicitly import the pieces you want, so the module doesn't need to load everything up when you just want a small part of it.
那是因为您有时需要显式导入所需的部分，因此当您只需要其中的一小部分时，模块不需要加载所有内容。
Hope this will help.
希望这会有所帮助。

from urllib.request import urlopen
from bs4 import BeautifulSoup
wiki = "https://en.wikipedia.org/wiki/List_of_state_and_union_territory_capitals_in_India"
page = urlopen(wiki)
soup = BeautifulSoup(page, "html.parser" ).encode('UTF-8')
print (soup)
