Python version 3.6.2
Use the ftp package: pyftpdlib pip install pyftpdlib to download and install it.
The FTP protocol will be more advantageous in downloading and uploading files when the files are too large, and more convenient for resumable upload and progress monitoring. below is the official document

Using Object pools
Joa EbertIs right when he says that utilizing object pools can make your codePerform a lot faster. An object pool is just a container for a bunchPre-constructed objects that are kept in memory ready for use, ratherThan being repeatedly allocated and destroyed on demand.
Object pooling makes sense if:
You create dozens of short-lived objects in real-time applications like games
You need to store and share temporary data througho
