How to Make a Network Usage Monitor in Python

To make a network usage monitor in Python, you can use the psutil library to get information about network connections and data transfer rates. Here is an example code snippet:

import psutil
import time

def monitor_network():
    old_value = psutil.net_io_counters().bytes_sent + psutil.net_io_counters().bytes_recv
    while True:
        new_value = psutil.net_io_counters().bytes_sent + psutil.net_io_counters().bytes_recv
        bytes_per_second = (new_value - old_value) / 1
        old_value = new_value
        print("Current network usage: ", bytes_per_second, "bytes per second")
        time.sleep(1)

monitor_network()

Current network usage:  0.0 bytes per second
Current network usage:  16622.0 bytes per second
Current network usage:  290297.0 bytes per second
Current network usage:  31555.0 bytes per second
Current network usage:  11301.0 bytes per second
Current network usage:  10862.0 bytes per second
Current network usage:  2454.0 bytes per second
Current network usage:  20847.0 bytes per second
Current network usage:  200564.0 bytes per second
Current network usage:  107393.0 bytes per second

In this example, we define a function called monitor_network() that uses the psutil library to get the current number of bytes sent and received by the system through network connections. We use a while loop to continuously calculate the rate of data transfer in bytes per second and print the result to the console.

We sleep for 1 second between iterations to avoid consuming too much processing time.

You can modify this code to suit your specific monitoring requirements, such as tracking usage over a longer period or logging the data to a file.

Please note that network monitoring may require elevated privileges on some systems, and should be used responsibly and only with the appropriate permissions.
