Osx Update Python

Release Date: April 9, 2012 Note: A newer bugfix release, Mac os 10.10 release date. 2.7.4, is currently available.Its use is recommended over previous versions of 2.7. Python 2.7.3 was released on April 9, 2012. 2.7.3 includes fixes for several reported security issues in 2.7.2: issue 13703 (oCERT-2011-003, hash collision denial of service), issue 14234 (CVE-2012-0876, hash table collisions CPU usage DoS. Python 3 (released in 2008) is the newest version of Python, and most features have not changed. Most packages have been updated to Python 3 by now (2016). So, if your lab does not have a preference, I recommend using Python 3. There are a couple key differences for novice programmers: In Python 2, you can print with print 42 or print(42). For OSX users, python2.7 comes pre-installed in /usr/bin/ but any python versions that were downloaded and installed by a user are likely in /usr/local/bin/ (see OutOnAWeekend's comment). – David Skarbrevik Oct 12 '18 at 22:10.

[1](1, 2) The binaries for AMD64 will also work on processors that implement the Intel 64 architecture (formerly EM64T), i.e. the architecture that Microsoft calls x64, and AMD called x86-64 before calling it AMD64. They will not work on Intel Itanium Processors (formerly IA-64).
[2](1, 2) There is important information about IDLE, Tkinter, and Tcl/Tk on Mac OSX here. Also, on Mac OS X 10.6, if you need tobuild C extension modules with the 32-bit-only Python installed, you willneed Apple Xcode 3, not 4. The 64-bit/32-bit Python can use eitherXcode 3 or Xcode 4.
