How to route internet traffic via `Clash for Windows` (Ping from Python code is not working)

Question

from os import system
system("ping www.twitter.com")
system("ping www.yahoo.com")
system("ping www.facebook.com")

I am in China, and Twitter and Facebook are banned here. I can open them in the browser using Clash for Windows software.

I have to download tweets from Twitter. So I need to ping the websites using Python to get tweets. I cannot ping the websites though.

How do I make my Python code use the Clash for Windows.

Output of the above code:

Answer 1

You said in comment that you are using Clash, however Clash is not a VPN:

Clash - A rule-based tunnel in Go.

Features:

• Local HTTP/HTTPS/SOCKS server with authentication support
• VMess, Shadowsocks, Trojan, Snell protocol support for remote connections
• Built-in DNS server that aims to minimize DNS pollution attack impact, supports DoH/DoT upstream and fake IP.
• Rules based off domains, GEOIP, IP CIDR or ports to forward packets to different nodes
• Remote groups allow users to implement powerful rules. Supports automatic fallback, load balancing or auto select node based off latency
• Remote providers, allowing users to get node lists remotely instead of hardcoding in config
• Netfilter TCP redirecting. Deploy Clash on your Internet gateway with iptables.
• Comprehensive HTTP RESTful API controller

I'm not sure exactly how it works, my current understanding is that it allows you to use proxies.

Although it also has TUN mode as a "Premium Feature" (not sure what does it mean, I see no option to buy "Premium") which may work similarly to VPN, but I'm not sure:

Premium Features:

• TUN mode on macOS, Linux and Windows. Doc
• Match your tunnel by Script
• Rule Provider

Clash for Windows which you try to use, is GUI for Clash.

Documentation is available, but it is only in Chinese:

I tried to use it, but I don't know how to configure it. It didn't work at all.

I see many possible solutions:

1. You can switch to proper VPN. Paid VPNs are more recommended than free ones. Cost is typically 3-10$/month depending on offer. Alternatively you can try to setup OpenVPN on your own VPS, it may be a bit cheaper, but not necessarily.
2. You can configure your script to use proxy. Libraries like requests support it: Proxies with Python 'Requests' module
3. You can try to read Clash for Windows documentation to see if it is possible what you try to achieve. Maybe it is enough to turn on System Proxy as visible on screenshot above?
4. You can try to configure Clash in TUN mode. In my opinion it may be more difficult than solutions 1 and 2. If you prefer this way, I suggest to read Clash documentation thoroughly: https://github.com/Dreamacro/clash/wiki/premium-core-features#tun-device

If you can afford it, I recommend solution 1 in most use-cases. I understand that you prefer free solution, however servers are not free, somebody needs to incur costs of running them (hardware, electricity etc.)
