I ran python3 -m pip install -U discord.py but it only installed discord.py v0.16.x. How do I install the new discord.py rewrite v1.0? 
I uninstalled the old discord.py using pip uninstall discord.py and re-ran pip to install discord.py, only to get version v0.16.x again instead of the new v1.0 version.
If your also having trouble with all the above install python using the Microscoft Store and use the commands above in command prompt
