You can't use open() , but you could use the requests library to do it. 您不能使用open() ，但是可以使用requests库来完成。
import requests
url_to_txt_file = ""
print(requests.get(url_to_txt_file).text)
Alternatively, you could use urllib.request . 另外，您可以使用urllib.request 。
import urllib.request
url_to_txt_file = ""
print(urllib.request.urlopen(url_to_txt_file).read())

urllib2 can return a file-like object from a URL. urllib2可以从URL返回类似文件的对象。 Here is an example from the documentation : 这是文档中的示例：
>>> import urllib2
>>> f = urllib2.urlopen('http://www.python.org/')
>>> print f.read(100)
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<?xml-stylesheet href="./css/ht2html
There is even the option to build an 'opener' if you really must use the open method: 如果您确实必须使用open方法，甚至可以选择构建“ opener”：
proxy_handler = urllib2.ProxyHandler({'http': 'http://www.example.com:3128/'})
proxy_auth_handler = urllib2.ProxyBasicAuthHandler()
proxy_auth_handler.add_password('realm', 'host', 'username', 'password')
opener = urllib2.build_opener(proxy_handler, proxy_auth_handler)
# This time, rather than install the OpenerDirector, we use it directly:
opener.open('http://www.example.com/login.html')
