Why Does \'getaddrinfo Failed\' Occur in Bottlepy\'s Hello World Sample?

Understanding "getaddrinfo failed" Error

The "getaddrinfo failed" error typically indicates that the system is unable to resolve a hostname into its corresponding IP address. This error commonly occurs when attempting to establish network connections.

In the context of Bottlepy's hello world sample, this error is most likely encountered due to an unresolved hostname. When specifying the hostname in the socket.getaddrinfo() function, it is important to ensure that it can be successfully resolved to an IP address.

To address this issue, you can try replacing 'localhost' with '127.0.0.1' in the socket.getaddrinfo() function:

<code class="python">import socket
socket.getaddrinfo('127.0.0.1', 8080)</code>

This change forces the system to use the loopback address (127.0.0.1) instead of attempting to resolve 'localhost', which may avoid the "getaddrinfo failed" error if 'localhost' is not properly configured in your system.
