Release Date: Aug. 11, 2020
This is the first release candidate of Python 3.9
This release, 3.9.0rc1, is the penultimate release preview. Entering the release candidate phase, only reviewed code changes which are clear bug fixes are allowed between this release candidate and the final release. The second candidate and the last planned release preview is currently planned for 2020-09-14.
- When the download is complete, your Mac automatically opens the disk image for you. The disk image actually looks like a folder. Inside this folder, you see a number of files, including python.mpkg. The python.mpkg file is the one that contains the Python application. The text files contain information about the build, licensing, and any late.
- Navigate to the Python downloads page: Python downloads. Click on the link/button to download Python 2.7.x. Follow the installation instructions (leave all defaults as-is). Open your terminal again and type the command cd. Next, type the command python. The Python interpreter should.
- I'm trying to install CERN's ROOT module. It's already installed on the mac terminal but I wish to access it in python too. I have it saved in site-packages which I have checked is the correct directory where all of my other accessible modules: numpy, scipy, matplotlib etc are housed.

And now for something completely different
Announcer: (Eric Idle) Welcome to the 'Phone-In'. Today we have on our panel our resident Psychiatrist, a Psychiatrist who isn't resident but is staying with the other one because he can't bear to go home and a Psychiatrist who has lived with the first one but who when the second one arrived felt alienated and since has undergone a total personality change. Our subject tonight is Farming and our first caller is from Redding. (phone rings)
Woman: (Carol Cleveland) Hello.
Announcer: Hello. Welcome to 'Phone-In' what is your question to the panel?
Woman: Is Vic there?
Announcer: Is Vic there? Is Vic there, Doctor Rogers?
Rogers: (Graham Chapman) Well the problem here is a simple one. The caller wants to know if Vic is there... and in this case Vic, as far as I can tell...
Dibbs: (John Cleese) Can I interrupt, Alan?
Announcer: Yes, of course.
Dibbs: I agree with what Rogers was going to say. As far as we can tell, Vic isn't here. The only thing she can do is to keep calling and if Vic comes in we'll let her know.
