Do_get Python

Python Programming

Welcome to my blog! Today, I want to talk about the do_get function in Python. As a Python developer myself, I have encountered this function many times and it has proven to be quite useful in my projects.

The do_get function is a built-in method in the Python http.server module. It is used to handle GET requests in a simple HTTP server. When a client sends a GET request to the server, the do_get function is called to process the request and generate a response.

One of the great things about the do_get function is its simplicity. It takes two parameters: self and request. The self parameter refers to the instance of the server class, and the request parameter contains information about the incoming request.

Inside the do_get function, you can perform various operations to handle the request. For example, you can access the requested URL using the request.path attribute. You can also extract query parameters from the URL using the urlparse function from the urllib.parse module.

Once you have processed the request and generated the response, you can use the self.send_response method to send the HTTP response status code, such as 200 for a successful request. You can then use the self.send_header method to send any additional headers, and finally use the self.end_headers method to indicate the end of the headers.

After sending the headers, you can use the self.wfile.write method to send the actual response content. This can be a simple string, an HTML page, or even a file.

Now, let’s take a closer look at how the do_get function can be used in a real-world scenario. Imagine you are building a simple web server that serves static files. You can use the do_get function to handle GET requests and send the corresponding file back to the client.

import http.server

class MyServer(http.server.BaseHTTPRequestHandler):
    def do_get(self, request):
        # Process the request here
    def do_head(self, request):
        # Process the HEAD request here
    def do_post(self, request):
        # Process the POST request here
    # Other HTTP methods go here
    # Override the default do_GET method to use do_get
    def do_GET(self):
    # Override the default do_HEAD method to use do_head
    def do_HEAD(self):
    # Override the default do_POST method to use do_post
    def do_POST(self):

# Create an instance of the server class and start the server
server = http.server.HTTPServer(('localhost', 8000), MyServer)

In the code above, we define a custom server class that inherits from http.server.BaseHTTPRequestHandler. We override the do_GET, do_HEAD, and do_POST methods to use our custom do_get, do_head, and do_post methods, respectively.

This allows us to handle different types of HTTP requests using different methods, while still leveraging the functionality provided by the do_get function. This modular approach makes it easier to manage and organize our code.


The do_get function in Python provides a simple and efficient way to handle GET requests in an HTTP server. With its straightforward syntax and flexibility, it is a valuable tool for developers working on web applications or building custom servers.

By leveraging the power of the do_get function, we can process incoming requests, generate appropriate responses, and deliver a seamless experience to our users. Whether you are a seasoned Python developer or just starting with web development, understanding the do_get function is a key step in mastering server-side programming.
