python
import subprocess
def check_internet_connection():
try:
# Ping a reliable IP address to check internet connectivity
output = subprocess.check_output(['ping', '-c', '1', '8.8.8.8'])
if '1 packets transmitted, 1 received' in output.decode():
return True
else:
return False
except subprocess.CalledProcessError:
return False
if check_internet_connection():
print("Internet connection is working.")
else:
print("No internet connection.")
In the above code, we use the `subprocess` module to execute the `ping` command on a reliable IP address (here, ‘8.8.8.8’ which is Google’s public DNS server). The code then checks if the output contains the string ‘1 packets transmitted, 1 received’ to determine if the internet connection is working.
