Connecting to a web server in Python 3

Question

I am trying to connect to a web server in Python 3 and it just doesn't work! I wrote the following in my code editor VS Code and btw, I don't have telnet installed. So, here's my code:

import socket
mysock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
mysock.connect(('http://data.pr4e.org',80))

And the traceback I am getting:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
socket.gaierror: [Errno 11001] getaddrinfo failed

Any suggestions?

Are you doing this at such a low level on purpose? There are built-in and third-party modules that speak HTTP. — Chris

In any case, I don't think you should be including http://. Try just data.pr4e.org. — Chris

The error is saying name lookup fails, and for good reason. When using raw sockets, you mustn't put the http:// protocol in the hostname string.

mysock.connect(('http://data.pr4e.org', 80))

must be

mysock.connect(('data.pr4e.org', 80))
