Python programming language is widely used in web development specially in backend development. In this Python article, we will learn about “python -m SimpleHTTPServer” and also we will learn What is the equivalent of “python -m SimpleHTTPServer” in Python3.

What is “python -m SimpleHTTPServer”?
In Python 2,
"python -m SimpleHTTPServer" command is used to start a simple HTTP server using a module named as SimpleHTTPServer which comes pre-installed with Python programming language. This module provides a basic HTTP server for serving content from the current directory.
How to use “python -m SimpleHTTPServer” :
To use this command, open cmd/bash from the current working directory which you want to be served. Then run
python -m SimpleHTTPServer command. This will start HTTP server on port 8000 by default. Then open your browser and type:
http://loaclhost:8000 to access your content.
Port number can also be changed according to the user. Type Port number you want to use in the place of PORT
python -m SimpleHTTPServer PORT to serve files on different port number.
“python -m SimpleHTTPServer” in Python3
"python -m SimpleHTTPServer" is equivalent to
http.server in Python3. This “python -m SimpleHTTPServer” has been replaced with
http.server from Python version 3.

From Python3 onwards, the
http.server is being used to for web client-server communication. The
http.server module comes pre-installed with Python3 which provides a basic HTTP Server for serving content from a directory over HTTP.
To start an HTTP server using the
http.server module, open a terminal or command prompt and navigate to the directory that you want to serve. Then run the
python -m http.server command. This will start the HTTP server on port 8000 by default. You can then access the content in the directory by visiting http://localhost:8000 in a web browser.
You can also specify a different port number by including it as an argument. For example,
python -m http.server 8080 will start the HTTP server on port 8080.
Here is an example code to create a server in Python3 Using the http.server module.
# importing required modules. import http.server, socketserver # configuring port number. PORT = 3000 # inheriting from http.server.SimpleHTTPRequestHandler class MyHandler(http.server.SimpleHTTPRequestHandler): def do_GET(self): self.send_response(200) self.send_header("Content-type", "text/html") self.end_headers() self.wfile.write(b"Serving From Python http.server module.") # creating a new tcp server. with socketserver.TCPServer(("", PORT), MyHandler) as httpd: print("serving at port", PORT) # this will start the server. httpd.serve_forever()
serving at port 3000
In the above example code and output, you can see an HTTP server has been created on the localhost:3000 by using
http.server module which is equivalent of “python -m SimpleHTTPServer”. This serves the files and directories to port 3000 and can be accessed on browser.
Here we have a
MyHandler class which inherits from
http.server.SimpleHTTPRequestHandler. This class handles incoming HTTPS request.
Here we have a
do_GET() method in
MyHandler class, which is called by the server when the server receives an HTTP GET request. Then this method sends a response to the client which has a status code and body.
send_header() method is used to specify the MIME type of the body. Whereas, the
end_headers() is used to indicate end of HTTP headers.
Here wfile has been used to send the body to client.
Then we have created a new
TCPServer object, using socketserver module. The socketserver module comes pre-installed with Python3 which provides a number of classes that can be used to create network servers.
TCPServer class is a basic TCP server that listens for the connections and handles them using a separate thread for each client.
Then, The serve_forever() method starts the server and listens for requests indefinitely. To stop the server press
CTRL+C in cmd.
So In this Python article, of What is the equivalent of “python -m SimpleHTTPServer” in Python3, we learned that the
http.server is equivalent to the “python -m SimpleHTTPServer” in Python3. The SimpleHTTPServer module was used in Python2 for client-server communication. But after Python3, we use
http.server module for client-server communication. Also in this article we learned to create a basic server with the help of http.server and socketserver modules.
Make sure to practice with above examples, in order to have a better understanding of this problem. Thanks.
