• Mac Os X Update Python 2.7
• Mac Os X Python Virtualenv
• Mac Os X Upgrade Python 2.7

Installing applications on macOS and OS X computers is easy to do when deploying the apps as packages through the Terminal using the Installer command for quiet deployments across your network. The first release of the new OS — Mac OS X Server 1.0 — used a modified version of the Mac OS GUI, but all client versions starting with Mac OS X Developer Preview 3 used a new theme known as Aqua. Aqua was a substantial departure from the Mac OS 9 interface, which had evolved with little change from that of the original Macintosh operating.

Python 3.3.x has reached end-of-life. This is its final release.It is a security-fix source-only release.

Python 3.3.0 was released on 2012-09-29 and has been in security-fix-only mode since 2014-03-08. Per Python Development policy, all support for the 3.3 series of releases ended on 2017-09-29, five years after the initial release. This release, Python 3.3.7, was the final release for the 3.3 series.

After 2017-09-29, we no longer accept bug reports nor provide fixes of any kind for Python 3.3.x (third-party distributors of Python 3.3.x may choose to offer their own extended support). Because 3.3.x has long been in security-fix mode, 3.3.7 may no longer build correctly on all current operating system releases and some tests may fail. If you are still using Python 3.3.x, we strongly encourage you to upgrade to a more recent, fully supported version of Python 3; see https://www.python.org/downloads/.

Python 3.3 includes a range of improvements of the 3.x series, as well as easierporting between 2.x and 3.x.

• PEP 380, syntax for delegating to a subgenerator (yield from)
• PEP 393, flexible string representation (doing away with the distinctionbetween 'wide' and 'narrow' Unicode builds)
• A C implementation of the 'decimal' module, with up to 120x speedupfor decimal-heavy applications
• The import system (__import__) is based on importlib by default
• The new 'lzma' module with LZMA/XZ support
• PEP 397, a Python launcher for Windows
• PEP 405, virtual environment support in core
• PEP 420, namespace package support
• PEP 3151, reworking the OS and IO exception hierarchy
• PEP 3155, qualified name for classes and functions
• PEP 409, suppressing exception context
• PEP 414, explicit Unicode literals to help with porting
• PEP 418, extended platform-independent clocks in the 'time' module
• PEP 412, a new key-sharing dictionary implementation that significantlysaves memory for object-oriented code
• PEP 362, the function-signature object
• The new 'faulthandler' module that helps diagnosing crashes
• The new 'unittest.mock' module
• The new 'ipaddress' module
• The 'sys.implementation' attribute
• A policy framework for the email package, with a provisional (seePEP 411) policy that adds much improved unicode support for emailheader parsing
• A 'collections.ChainMap' class for linking mappings to a single unit
• Wrappers for many more POSIX functions in the 'os' and 'signal' modules, aswell as other useful functions such as 'sendfile()'
• Hash randomization, introduced in earlier bugfix releases, is nowswitched on by default

This is the fifth maintenance release of Python 3.8

Note: The release you're looking at is Python 3.8.5, a bugfix release for the legacy 3.8 series. Python 3.9 is now the latest feature release series of Python 3. Get the latest release of 3.9.x here.

3.8.5 has been released out of schedule due to important security content. For details please consult the change log. Please upgrade at your earliest convenience.

Major new features of the 3.8 series, compared to 3.7

• PEP 572, Assignment expressions
• PEP 570, Positional-only arguments
• PEP 587, Python Initialization Configuration (improved embedding)
• PEP 590, Vectorcall: a fast calling protocol for CPython
• PEP 578, Runtime audit hooks
• PEP 574, Pickle protocol 5 with out-of-band data
• Typing-related: PEP 591 (Final qualifier), PEP 586 (Literal types), and PEP 589 (TypedDict)
• Parallel filesystem cache for compiled bytecode
• Debug builds share ABI as release builds
• f-strings support a handy = specifier for debugging
• continue is now legal in finally: blocks
• on Windows, the default asyncio event loop is now ProactorEventLoop
• on macOS, the spawn start method is now used by default in multiprocessing
• multiprocessing can now use shared memory segments to avoid pickling costs between processes
• typed_ast is merged back to CPython
• LOAD_GLOBAL is now 40% faster
• pickle now uses Protocol 4 by default, improving performance

There are many other interesting changes, please consult the 'What's New' page in the documentation for a full list.

Mac Os X Update Python 2.7

Windows users

• 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.

macOS users

• For Python 3.8, we provide one installer: 64-bit-only that works on macOS 10.9 (Mavericks) and later systems.
• Please read the 'Important Information' displayed during installation for information about SSL/TLS certificate validation and the running the 'Install Certificates.command'.

And now for something completely different

Mac Os X Python Virtualenv

Mac Os X Upgrade Python 2.7

Our universe itself keeps on expanding and expanding,
In all of the directions it can whiz;
As fast as it can go, at the speed of light, you know,
Twelve million miles a minute and that's the fastest speed there is.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth;
And pray that there's intelligent life somewhere out in space,
'Cause there's bugger all down here on Earth!
