Python 2.7.7 is the last release for which binary installers will be released on python.org that support Mac OS X 10.3.9 (Panther) and 10.4.x (Tiger) systems. For Python 2.7.7 only, we are providing three OS X binary installers: the unchanged 10.6+ 64-bit/32-bit format, the deprecated 10.3+ 32-bit-only format, and the newer 10.5+ 32-bit-only.
Apple® announced the newest in its Power Mac® G5 desktop line, featuring dual 64-bit PowerPC G5 processors running up to 2.7 GHz and including Mac OS® X version 10.4 'Tiger.' The new Power Mac G5 line features higher performance graphics options, more memory and built-in support for Apple's 30-inch Cinema HD Display on the 2.7 GHz model. 2.7.8 Documentation » The Python Standard Library » 36. The method will return False if the window manager is not available, for instance when running on Mac OS X Server or when logged in via ssh, or when the current interpreter is not running from a fullblown application bundle.
This module provides access to MacOS specific functionality in the Pythoninterpreter, such as how the interpreter eventloop functions and the like. Usewith care.
Note the capitalization of the module name; this is a historical artifact.
Always 'macho', from Python 2.4 on. In earlier versions of Python the valuecould also be 'ppc' for the classic Mac OS 8 runtime model or 'carbon'for the Mac OS 9 runtime model.
The way the interpreter has been linked. As extension modules may beincompatible between linking models, packages could use this information to givemore decent error messages. The value is one of 'static' for a staticallylinked Python, 'framework' for Python in a Mac OS X framework, 'shared'for Python in a standard Unix shared library. Older Pythons could also have thevalue 'cfm' for Mac OS 9-compatible Python.
This exception is raised on MacOS generated errors, either from functions inthis module or from other mac-specific modules like the toolbox interfaces. Thearguments are the integer error code (the OSErr value) and a textualdescription of the error code. Symbolic names for all known error codes aredefined in the standard module macerrors.
Return the textual description of MacOS error code errno.
On Mac OS X the string is simply printed to stderr (on older Mac OS systems moreelaborate functionality was available), but it provides a convenient location toattach a breakpoint in a low-level debugger like gdb.
Note
Not available in 64-bit mode.
Ring the bell.
Get the number of clock ticks (1/60th of a second) since system boot.
Return the file creator and file type as two four-character strings. The fileparameter can be a pathname or an FSSpec or FSRef object.
Note
It is not possible to use an FSSpec in 64-bit mode.
Set the file creator and file type. The file parameter can be a pathname or anFSSpec or FSRef object. creator and type must be four characterstrings.
Note
It is not possible to use an FSSpec in 64-bit mode.
Open the resource fork of a file. Arguments are the same as for the built-infunction open(). The object returned has file-like semantics, but it isnot a Python file object, so there may be subtle differences.
Checks whether the current process has access to the window manager. The methodwill return False if the window manager is not available, for instance whenrunning on Mac OS X Server or when logged in via ssh, or when the currentinterpreter is not running from a fullblown application bundle. A script runsfrom an application bundle either when it has been started withpythonw instead of python or when running as an applet.
Opens a splash screen by resource id. Use resourceid 0 to closethe splash screen.
This guide shows how to install the latest 2.x release of Python and all important Python packaging / sandboxing utilities like Pip and Virtualenv under Mac OS X 10.10 Yosemite.
I am using Homebrew to install pre-compiled software. I checked Homebrew 4 years ago and it had issue but now in 2015 it became a more mature solution for the installation of complex Unix software under Mac.
Let's start.
1. Install Homebrew
Open Terminal.app and type (copy & paste) the following lines to install Homebrew and to check if it worked:
the brew help command should display a list of brew (= Homebrew) commands as validation of a successful installation of Homebrew.
2. Install Python 2.7.9 & Pip
Enter in Terminal.app:
The newly installed Python version should be displayed. That was easy!
Now you need update Pip which is a Python package manager. It was already installed together with Python.
3. Update Pip
Enter in Terminal.app:
The Pip version is displayed and can be used to install and upgrade all further Python packages and libraries.
But one key component of every Python development environment is still missing: Virtualenv. Virtualenv is something like a sandboxing system which separates applications (your Python projects) and their installed packages from each other. That separation is very important due because Python has its own internal (not so easy to understand) package dependency system.
All that becomes important latest when you want to deploy your project and its dependencies so better do sandboxing from Day 1.
4. Install Virtualenv & Virtualenvwrapper
Let's start sandboxing by installing the necessary tool Virtualenv ('virtual environments'). Enter in Terminal.app:
Celeste 2.7 Mac Os Downloads
Correct, you just uninstalled it before installing! That is necessary because we also install Virtualenvwrapper which may require a certain Virtualenv version.
The second part of all the entered commands created a hidden file in your home directory which contains the Virtualenv settings. And as last step you created autostart magic of all that.
5. Finished, now let's test!
Congratulations, you successfully installed Python 2.7.9 (or later), Pip and all sandboxing tools under Mac OS X 10.10 Yosemite.
Now it is time to create our first test project and sandbox (often called virtualenv but that may be confusing due to the Virtualenv project).
Enter in Terminal.app:
You created a new folder called PythonProjects in your home folder and a subfolder called TestProject. You can browse that still empty folder in Finder, too.
Now it is time to create the sandbox of TestProject which we call test1. Enter in Terminal.app:
Celeste 2.7 Mac Os X
You just made / created a virtualenv sandbox called test1. Now it is necessary to work on that sandbox before you do any Pip operation.
Good to know: The name of the active Sandbox is displayed directly at the beginning of the Terminal command prompt which is very helpful to see if you are currently inside a sandbox or not!
To leave / close the sandbox just type deactivate. So let's continue with the test by activating the sandbox, installing an the Python package PyTest (just as example), test all that and deactivate / close the sandbox:
The package PyTest was installed because the call at line 3 displayed the version. Now we left the sandbox and if we do the same call again then the package should not be available anymore (because we just installed it inside the test1 sandbox) and an ImportError is displayed:
So always keep in mind to enter workon before you do any Pip operation or start working on a project. Also check the installed Virtualenvwrapper, it comes with some further handy commands and automation.
And finally, delete the sandbox because it was just a test:
I hope you enjoyed that guide and it was helpful. Please leave a comment if it worked and also if not.
Thanks!
