  • There are now 'web-based' installers for Windows platforms; the installer will download the needed software components at installation time.
  • There are redistributable zip files containing the Windows builds, making it easy to redistribute Python as part of another software package. Please see the documentation regarding Embedded Distribution for more information.
  • We provide two binary installer options for download. The default variant is 64-bit-only and works on macOS 10.9 (Mavericks) and later systems. Changed in 3.7.4 The 64-bit/32-bit variant that also works on very old versions of macOS, from 10.6 (Snow Leopard) on, is now deprecated and will no longer be provided in future releases; see the macOS installer ReadMe file for more info. Both variants come with batteries-included versions of Tcl/Tk 8.6 for users of IDLE and other tkinter-based GUI applications; third-party and system versions of Tcl/Tk are no longer used.
  • Both installer variants include private copies of OpenSSL. Please carefully read the Important Information displayed during installation for information about SSL/TLS certificate validation and the Install Certificates.command. Changed in 3.7.4 OpenSSL has been updated from 1.1.0 to 1.1.1.

Mac Upgrade Python To 3.7 Code

Edited: 2020-12-28 16:53:45 UTC

Instead of using below method please consider adding a new/multi python versionon your system. According the python version you want, look at one of thearticles below:

Since below method may cause system error: probably breakapt or misconfiguration of thesystem.


In this article, we upgrade to python 3.7 from python 3.6 and configure itas the default version of python.

I was just trying to upgrade my python and I find it a little bit hard to do.Python 3.6 is the default version that comes with Ubuntu 18.04/18.10 But the latestversion is Python 3.8. So it would be better to upgrade one major version.

So lets start:

Step 0: Check the current python version

Run below command to test the current version installed of python.

Output will be like:

Step 1: Install python3.7

Install python by typing:


Step 2: Add python 3.6 & python 3.7 to update-alternatives

Mac upgrade python to 3.7 free

Step 3: Update python 3 to point to python 3.7

By default, Python 3.6 is pointed to Python 3. That means when we run python3 itwill execute as python3.6 binary but we want to execute this as python3.7.

Mac upgrade python to 3.7 free

Type this command to configure python3:

You should get the above output. Now type 2 and hit enter for Python 3.7.Remember the selection number may differ so choose the selection number which isfor Python 3.7.

Alternative update python 3 to point to python3.7

/usr/bin/python3 is just a symlink. Delete it and make a new symlink topython3.7:

Step 4: Test the new version of python3

All done!
