We often use the network is based on tcp, So use tcping more accurately.

The return code can be catch by some real-time test tools. Following is an example:
import subprocess as sp
# Print the return code (status=0 mean ping success)
status = sp.call(['tcping', '-c', '1', '-t', '1', 'github.com'], stdout=sp.DEVNULL, stderr=sp.DEVNULL)
print(status)
# OR print the full message
status = sp.run(['tcping', '-c', '1', '-t', '1', 'github.com'], stdout=sp.DEVNULL, stderr=sp.DEVNULL)
print(status)Huh, I just want to check my VPS's network status.
