I was studying https://github.com/GoogleCloudPlatform/storage-signedurls-python
The sample uses requests.Session().get() and requests.Session().put() to implement the download/upload requests.
I found some link How can I upload files asynchronously? but it didn't seem fit the above python sample.
Is there any way like registering an event handler in requests.Session(), and getting the progress in that handler?
