Python: How to Test Internet Speed

speedtest

Probably, you have used the speedtest website before, but did you know that speedtest has a python library.
In this tutorial, We will learn to use the speedtest library to test your internet Speed. We'll also learn how to use speedtest command lines.

Let's get started.

Speedtest instalation

To install speedtest via pip, follow this command:

pip install speedtest-cli

Test internet speed (script)

After installing the speedtest package. Now, let's see how to use it with the code.

In the following code, I'll test my internet download speed.

import speedtest
 
# Speed test
st = speedtest.Speedtest()
 
# Download Speed
ds = st.download()
 
print(ds)
 

let me explain.
First, we import the speedtest package. Then, called Speedtest() class. Next, test my download speed using the download() method. Finally, print the result.

Output:

3422459.073187817

As you can see, the internet speed is in Bytes . To make it readable, we'll use the following function.

def humansize(nbytes):
    suffixes = ['B', 'KB', 'MB', 'GB', 'TB', 'PB']
    i = 0
    while nbytes >= 1024 and i < len(suffixes)-1:
        nbytes /= 1024.
        i += 1
    f = ('%.2f' % nbytes).rstrip('0').rstrip('.')
    return '%s %s' % (f, suffixes[i])
 
#Readable
print(humansize(ds))
 
 

Output:

3.56 MB

Now, let's test our upload speed using the upload() method.

import speedtest
 
# Speed test
st = speedtest.Speedtest()
 
# Upload speed
us = st.upload()
 
print(us)
 
#Readable
print(humansize(us))
 

Output:

386382.6586620888
301.51 KB

Speedtest command lines

Speedtest also provides the command lines for testing our internet speed.

Usage:

Help command:

speedtest-cli -h

Output:

usage: speedtest-cli [-h] [--no-download] [--no-upload] [--single] [--bytes]
                     [--share] [--simple] [--csv]
                     [--csv-delimiter CSV_DELIMITER] [--csv-header] [--json]
                     [--list] [--server SERVER] [--exclude EXCLUDE]

                     [--secure] [--no-pre-allocate] [--version]
 
Command line interface for testing internet bandwidth using speedtest.net.

Test Internet Speed:

speedtest-cli

Output:

Retrieving speedtest.net configuration...
Testing from xxx Telecom (196.89.30.99)...
Retrieving speedtest.net server list...

This command above tests ping , download speed, and upload speed.

Test Internet Speed: with the share link:

speedtest-cli --share
