This package will install Python $FULL_VERSION for Mac OS X

$ARCHITECTURES.

Installing on OS X 10.8 (Mountain Lion) or later systems
|
|
========================================================
|
|
|
|
If you are attempting to install on an OS X 10.8+ system, you may
|
|
see a message that Python can't be installed because it is from an
|
|
unidentified developer. This is because this Python installer
|
|
package is not yet compatible with the Gatekeeper security feature
|
|
introduced in OS X 10.8. To allow Python to be installed, you
|
|
can override the Gatekeeper policy for this install. In the Finder,
|
|
instead of double-clicking, control-click or right click the "Python"
|
|
installer package icon. Then select "Open using ... Installer" from
|
|
the contextual menu that appears.
|

Update your version of Tcl/Tk to use IDLE or other Tk applications
|
|
==================================================================
|
|
|
|
To use IDLE or other programs that use the Tkinter graphical user
|
|
interface toolkit, you may need to install a newer third-party version
|
|
of the Tcl/Tk frameworks. Visit http://www.python.org/download/mac/tcltk/
|
|
for current information about supported and recommended versions of
|
|
Tcl/Tk for this version of Python and of Mac OS X.
|
|
|
|
**NEW* As of Python 3.4.0b1:
|
|
|
|
New Installation Options and Defaults
|
|
=====================================
|
|
|
|
The Python installer now includes an option to automatically install
|
|
or upgrade pip, a tool for installing and managing Python packages.
|
|
This option is enabled by default and no Internet access is required.
|
|
If you do not want the installer to do this, select the "Customize"
|
|
option at the "Installation Type" step and uncheck the "Install or
|
|
ugprade pip" option.
|
|
|
|
To make it easier to use scripts installed by third-party Python
|
|
packages, with pip or by other means, the "Shell profile updater"
|
|
option is now enabled by default, as has been the case with Python
|
|
2.7.x installers. You can also turn this option off by selecting
|
|
"Customize" and unchecking the "Shell profile updater" option. You
|
|
can also update your shell profile later by launching the "Update
|
|
Shell Profile" command found in the /Applications/Python $VERSION
|
|
folder. You may need to start a new terminal window for the
|
|
changes to take effect.
|
|
|
|
Python.org Python $VERSION and 2.7.x versions can both be installed and
|
|
will not conflict. Command names for Python 3 contain a 3 in them,
|
|
python3 (or python$VERSION), idle3 (or idle$VERSION), pip3 (or pip$VERSION), etc.
|
|
Python 2.7 command names contain a 2 or no digit: python2 (or
|
|
python2.7 or python), idle2 (or idle2.7 or idle), etc. If you want to
|
|
use pip with Python 2.7.x, you will need to download and install a
|
|
separate copy of it from the Python Package Index
|
|
(https://pypi.python.org/pypi).
|
|
|
|
Using this version of Python on OS X
|
|
====================================
|
|
|
|
Python consists of the Python programming language interpreter, plus
|
|
a set of programs to allow easy access to it for Mac users including
|
|
an integrated development environment, IDLE, plus a set of pre-built
|
|
extension modules that open up specific Macintosh technologies to
|
|
Python programs.
|
|
|
|
The installer puts applications, an "Update Shell Profile" command,
|
|
and a link to the optionally installed Python Documentation into the
|
|
"Python $VERSION" subfolder of the system Applications folder,
|
|
and puts the underlying machinery into the folder
|
|
$PYTHONFRAMEWORKINSTALLDIR. It can
|
|
optionally place links to the command-line tools in /usr/local/bin as
|
|
well. Double-click on the "Update Shell Profile" command to add the
|
|
"bin" directory inside the framework to your shell's search path.
|
|
|
|
You must install onto your current boot disk, even though the
|
|
installer may not enforce this, otherwise things will not work.
|
|
|
|
You can verify the integrity of the disk image file containing the
|
|
installer package and this ReadMe file by comparing its md5 checksum
|
|
and size with the values published on the release page linked at
|
|
http://www.python.org/download/
|
|
|
|
Installation requires approximately $INSTALL_SIZE MB of disk space,
|
|
ignore the message that it will take zero bytes.
