Python download file requests
If you use Python regularly, you might have come across the wonderful requests library. I use it almost everyday to read urls or make POST requests. In this post, we shall see how we can download a large file using the requests module with low memory consumption. If we use the stream parameter and set it to Truethe download will not immediately start.
If we set stream to Falsepython download file requests, all the content is downloaded immediately and put into memory. If the file size is large, this can soon cause issues with higher memory consumption. On the other hand — if we set stream to Truethe content is not downloaded, python download file requests, but the headers are downloaded and the connection is kept open. We can now choose to proceed downloading the file or simply cancel it. But we must also remember that if we decide to stream the file, the connection will remain open and can not go back to the connection pool.
So we should carefully choose where we should stream. And we should take proper care to close the connections and dispose any unused resources in such scenarios. By setting the stream parameter, we have delayed the download and avoided taking up large chunks of memory.
The headers have been downloaded but the body of the file still awaits retrieval. We can now get the data by accessing the content property or choosing to iterate over the content. Accessing the content directly would read the entire response data to memory at once. That is a scenario we want to avoid when our target file is quite large. So we are left with the choice to iterate over the content. Either way, the entire file python download file requests not be loaded into memory and keep the memory usage down.
The code should be self explanatory. We are opening the url with stream set to True. Then we iterate over the content, chunk by chunk and write the data python download file requests the file. Thanks for this. You can also use this pip package to achieve the same. Your email address will not be published. Iterating The Content By setting the stream parameter, python download file requests, we have delayed the download and avoided taking up large chunks of memory. Code Example.
