Python waiting for file to download

Attention geek! Strengthen your foundations with the Python Programming Foundation Course and learn the basics. Python time module 1 A General sleep function. Python has a module named time. This module gives several useful functions to control time-related tasks. The argument may be a floating-point number to indicate more precise sleep time.

This is the most common method used because of its ease of use and the fact that it is platform independent. The implementation is given below: Example: Python3 First import time module. But for single-threaded programs sleep function suspends the thread and the whole process. The implementation is given below: Example: Python3. Using simple input We all know that the input function helps to take data from users. Skip to content. Change Language.

Essentially this just waits for the correct number of files as well. The general idea here would be to wait until a file would appear in your "Downloads" directory. This is a combination of a few solutions. I didn't like that I had to scan the entire downloads folder for a file ending in "crdownload".

This code implements a function that pulls the newest file in downloads folder. Then it simply checks if that file is still being downloaded. Used it for a Selenium tool I am building worked very well.

You can create a thread say thread1 from main thread and initiate your download here. Now, create some another thread, say thread2 and in there ,let it wait till thread1 completes using join method. Now here,you can continue your flow of execution after download completes. Still make sure you dont initiate your download using selenium, instead extract the link using selenium and use requests module to download.

Download using requests module. As answered before, there is no native way to check if download is finished. So here is a helper function that does the job for Firefox and Chrome.

One trick is to clear the temp download folder before start a new download. Also, use native pathlib for cross-platform usage. This works if you are trying to check if a set of files more than one have finished downloading. With Chrome, files which have not finished downloading have the extension. If you set your download directory properly, then you can wait until the file that you want no longer has this extension.

In principle, this is not much different to waiting for file to exist as suggested by alecxe - but at least you can monitor progress in this way. So redirect the function that starts the download. After that rename it. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?

One solution will be to make the download by grabbing the link and using the request module without going through the browser's download process.

This should help getting the file link since, the program needs to define the same to save the file — unityJarvis. Unfortunately, the href is not always available, and the link can be created after a certain time, when you go to the download page, by waiting for the server to serve the file. But perhaps, if it is possible to intercept the download link from the selenium to the request, I would get the name of the file, and just look for this file with a unique name in the download folder.
