This allows us to skip downloading files which weren't meant to be downloaded. That way involved just fetching the headers of a url before actually downloading it. I looked into the requests documentation and found a better way to do it. So if the file is large, this will do nothing but waste bandwidth. It works but is not the optimum way to do so as it involves downloading the file for checking the header. Headers usually contain a Content-Type parameter which tells us about the type of data the url is linking to.Ī naive way to do it will be - r = requests.get(url, allow_redirects= True) To solve this, what I did was inspecting the headers of the URL.

When the URL linked to a webpage rather than a binary, I had to not download that file and just keep the link as is. This was one of the problems I faced in the Import module of Open Event where I had to download media from certain links. If you said that a HTML page will be downloaded, you are spot on.

What do you think will happen if the above code is used to download it ? Now let's take another example where url is. The above code will download the media at and save it as google.ico. Open( 'google.ico', 'wb').write(r.content) R = requests.get(url, allow_redirects= True)

Let's start with baby steps on how to download a file using requests - import requests I will write about methods to correctly download binaries from URLs and set their filenames. I will be using the god-send library requests for it. Run the code and you should see image1.png created in the same directory as the main.This post is about how to efficiently/correctly download files from URLs using Python. png extension, meaning that this is a URL to a specific image.įor the headers we are only using the User-Agent request header which lets the servers identify the application of the requesting user agent (a computer program representing a person, like a browser or an app accessing the Webpage). The function to download an image from URL is ready and now we just need to define the url, file_name, and headers, and then run the code.įor example, in one of the previous tutorials, we used some sample images, and you can find one of them here. We are going to check if the response code is 200, and if it is, then we will save the image (which is the content of the request), otherwise we will print out the response code: If the HTTP request has been successfully completed, we should receive Response code 200 (you can learn more about response codes here). Response = requests.get(url, headers=headers) Now we can send a GET request to the URL along with the headers, which will return a Response (a server’s response to an HTTP request): headers – the dictionary of HTTP Headers that will be sent with the requestĭef download_image(url, file_name, headers):.Here, we will assume you have the URL of the specific image (and not just a webpage).Īs the first step, we will import the required dependency and define a function we will use to download images, which will have 3 inputs: In this section we will learn how to download an image from URL using Python.

If you don’t have it installed, please open “Command Prompt” (on Windows) and install it using the following code: Requests is a simple Python library that allows you to send HTTP requests. To continue following this tutorial we will need the following Python library: requests.

The training and testing images are usually either available locally or are downloaded from different websites. The tasks and automations range from similar image processing to more advanced projects like text extraction. Working with images in Python became a very popular topic in the recent years. In this tutorial we will explore how to download image from URL using Python.
