Python 2.7.3

Note: A newer bugfix release, 2.7.4, is currently available. Its use is recommended over previous versionsof 2.7.

Python 2.7.3 was released on April 9, 2012. 2.7.3 includes fixes for severalreported security issues in 2.7.2: issue 13703 (oCERT-2011-003, hashcollision denial of service), issue 14234 (CVE-2012-0876, hash tablecollisions CPU usage DoS in the expat library), issue 14001 (CVE-2012-0845,SimpleXMLRPCServer denial of service), and issue 13885 (CVE-2011-3389,disabling of the CBC IV attack countermeasure in the _ssl module).

The Python 2.7 series is scheduled to be the last major version in the 2.xseries before 2.x moves into an extended maintenance period. The 2.7 seriescontains many of the features that were first released in Python 3.1.Improvements in this release include:

  • An ordered dictionary type
  • New unittest features including test skipping, new assert methods, and testdiscovery
  • A much faster io module
  • Automatic numbering of fields in the str.format() method
  • Float repr improvements backported from 3.x
  • Tile support for Tkinter
  • A backport of the memoryview object from 3.x
  • Set literals
  • Set and dictionary comprehensions
  • Dictionary views
  • New syntax for nested with statements
  • The sysconfig module

We currently support these formats for download:

  • Mac OS X 64-bit/32-bit x86-64/i386 Installer (2.7.3) for Mac OS X 10.6 and 10.7[2](sig).[You may need an updated Tcl/Tk install to run IDLE or use Tkinter,see note 2 for instructions.]
  • Mac OS X 32-bit i386/PPC Installer (2.7.3) for Mac OS X 10.3 through 10.6[2](sig).

The source tarballs are signed with Benjamin Peterson's key (fingerprint: 12EF3DC3 8047 DA38 2D18 A5B9 99CD EA9D A413 5B38). The Windows installer was signedby Martin von Löwis' public key, which has a key id of 7D9DC8D2.

[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.

Installation Instructions

All supported versions of Python include the Python package managementtool pip, which allows an easy installation from the command line onall platforms. Try:

For updating an older version of Biopython try:

This will remove older versions of Biopython and NumPy before it installsthe recent versions.

Should you wish to uninstall Biopython:

If pip is not already installed you may need to update your Python, but first try:

If you need to install under a specific version of Python, try somethinglike this:

On Windows, by default python and pip are not on the PATH.You can re-install Python and tick this option, or give the full path instead.Try something like this, depending on where your copy of Python is installed:

Other packages

While we generally recommend using pip to install Biopython usingthe wheel packages we provide on PyPI (as above), there are alsoBiopython packages for Conda, Linux, etc.

Installation from Source

Installation from source requires an appropriate C compiler, for exampleGCC on Linux, and MSVC on Windows.For Mac OS X, or as it is now branded, macOS, if you want tocompile Biopython from source you will need to have installed Apple’scommand line tools, which can de done with the terminal command:

This will offer to install Apple’s XCode development suite - you can, butit is not needed and takes a lot of disk space.

You can then download and unzip a Biopython source code release, or getour code from GitHub. Then run:

or:

If you are still stuck, sign up to the Biopython mailinglist and ask for help there.

Required Software

  • Python 3.6, 3.7 or 3.8 or PyPy,including the Python development header files like python.h
  • C compiler (if compiling fromsource) Youneed a C compiler supported by setuptools, gcc will work fine onUNIX-like platforms. This is not needed on Windows if using thecompiled packages provided. On Mac OS, you should installApple’s the compiler tools as described above.
  • NumPy (Numerical Python).

Optional Software

Some parts of Biopython use the following additional python libraries:

  • ReportLab – used for pdfgraphics code
  • psycopg – used forBioSQL with a PostgreSQL database
  • mysql-connector– used for BioSQL with a MySQL database
  • MySQLdb – Analternative MySQL library used by BioSQL

In addition Biopython includes wrapper code for calling a number ofthird party command line tools including:

  • Wise2 – for command line tool dnal
  • NCBI StandaloneBLAST – commandline tool for running BLAST on your local machine
  • Clustalw –command line tool for building sequence alignments
  • SIMCOAL2 andFDist – commandline tools for population genetics
  • EMBOSS – lots of useful commandline tools.

Recent releases of Biopython require NumPy (and not Numeric). Version 1.76 is the last release to support Python 2.7 and 3.5, all later releases require Python 3.6 or greater:

Please note that Biopython 1.48 and older require the Numeric library,not its replacement NumPy. Windows installers for Python 2.4 and olderare available from the NumericalPython website. A Windowsinstaller for Numeric 24.2 for Python 2.5 is available here:

  • Numeric-24.2.win32-py2.5.exe446 Kb - Windows Installer for Python 2.5

Please note that Biopython 1.48 and older used mxTextTools2.0in some of the parsers. There were a few niggles with mxTextTools 3.0,so ideally install the older mxTextTools 2.0.
