If you need Python package isolation on a per-project basis, because you have conflicting sets of packages specified for different projects, you can use virtualenv to set up separate environments. The virtualenv tool establishes a clean room Python installation, either based upon the current version of Python in use, or a version specified on the command line.

Change Python Version Mac
Python2 and Python3 are different programs. Many programs upgrade from the older version to the newer one. However, Python 2.7.x installations can be run separately from the Python 3.7.x version on the same system. Python 3 is not entirely backward compatible. To check for Python 2.7.x: python ––version. To check the version of Python 3. Depends on what you're going to use python for. Things like scripts/back-end APIs should be fine (I'm doing these sort of tasks on my 2015 Air), but anything that involves heavy computation (training a neural net for example), or anything that requires a large amount of compilation will probably be better on the Pro.
Python for Mac OS X
Python comes pre-installed on Mac OS X so it is easy to startusing. However, to take advantage of the latest versions ofPython, you will need to download and install newer versionsalongside the system ones. The easiest way to do that is toinstall one of the binary installers for OS X from thePython Download page. Installers areavailable for the latest Python 3 and Python 2 releases thatwill work on all Macs that run Mac OS X 10.5 and later.
Python releases include IDLE, Python's built-in interactivedevelopment environment. If you download and install Pythonfrom the release page, you may also need to download and installa newer version of Tcl/Tk for OS X. See theIDLE and Tkinter on OS X page formore information.
You can run a Python interpreter by double-clicking onApplications / Utilities / Terminal and typing python3 (if you'veinstalled a version of Python 3) or python (to use Python 2) inthe window that opens up. You can also launch IDLE for the Pythonversion you have installed by double-clicking its icon inthe appropriate Python version folder in the Applications folderor you can also just type idle3 or idle in a terminal window.
There are many thousands of additional Python software packagesavailable through PyPI, the PythonPackage Index. We recommend you use thepip tool to simplifyinstalling and managing additional packages. pip is includedwith Python 3.4 releases; for earlier releases, follow the pipinstall instructions.

Among the packages available through PyPI are some that arespecifically for OS X environments. Among these are:
- pyobjc which providesa bridge between Python and Objective-C, allowing you to writefull-featured native Cocoa applications in pure Python.
- py2app which allowsyou to make standalone OS X double-clickable application bundlesand plugins from Python scripts.
