Python for Mac OS X
Changing the default python executable's version system-wide could break some applications that depend on python2. However, you can alias the commands in most shells, Since the default shells in macOS (bash in 10.14 and below; zsh in 10.15) share a similar syntax.

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:
Oct 01, 2019 To check for Python 2.7.x: python ––version. To check the version of Python 3 software: python3 ––version. Most systems differentiate Python 2 as python and Python 3 as python3. If you do not have Python 2, your system may use the python command in place of python3. Python command will open a Python interpreter, where you can't run the python hello.py command so you got the syntax error (to run hello.py in python shell you need execfile (hello.py)) to quit the Python interpreter, type ctrl+d and than python hello.py to execute your hello world script. For most Unix systems, you must download and compile the source code. The same source code archive can also be used to build the Windows and Mac versions, and is the starting point for ports to all other platforms. Download the latest Python 3 and Python 2 source.
- 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.

Release Date: June 27, 2018
Python 3.7.0 was the initial feature release of Python 3.7.
There are now newer bugfix releases of Python 3.7 that supersede 3.7.0 and Python 3.8 is now the latest feature release of Python 3. Get the latest releases of 3.7.x and 3.8.x here. We plan to continue to provide bugfix releasesfor 3.7.x until mid 2020 and security fixes until mid 2023.
Among the major new features in Python 3.7 are:
Python Shell Download For Mac
- PEP 539, new C API for thread-local storage
- PEP 545, Python documentation translations
- New documentation translations: Japanese,French, andKorean.
- PEP 552, Deterministic pyc files
- PEP 553, Built-in breakpoint()
- PEP 557, Data Classes
- PEP 560, Core support for typing module and generic types
- PEP 562, Customization of access to module attributes
- PEP 563, Postponed evaluation of annotations
- PEP 564, Time functions with nanosecond resolution
- PEP 565, Improved DeprecationWarning handling
- PEP 567, Context Variables
- Avoiding the use of ASCII as a default text encoding (PEP 538, legacy C locale coercionand PEP 540, forced UTF-8 runtime mode)
- The insertion-order preservation nature of dict objects is now an official part of the Python language spec.
- Notable performance improvements in many areas.
Please see What’s New In Python 3.7 for more information.
- PEP 537, 3.7 Release Schedule
- Report bugs at https://bugs.python.org.
- Help fund Python and its community.
- The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the 'x64' architecture, and formerly known as both 'EM64T' and 'x86-64'.)
- 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.
- For 3.7.0, 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. We also continue to provide a 64-bit/32-bit variant that works on all versions of macOS from 10.6 (Snow Leopard) on. Both variants now 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. Consider using the new 10.9 64-bit-only installer variant, unless you are building Python applications that also need to work on older macOS systems.
- Both python.org installer variants include private copies of OpenSSL 1.1.0. Please carefully read the Important Information displayed during installation for information about SSL/TLS certificate validation and the Install Certificates.command.
