Python Installation

Python Installation


Python is a core element of the TACTIC application. The TACTIC application has been developed around the the python programming language.

The installations of both python and supporting modules is a reqirement in a successful installation of TACTIC. Although the TACTIC core files can exist on the host machine, it is the existance of both Python and the supporting modules.

Python Version

Python 2.5 is the defacto standard for deployments of the TACTIC application. 2.6 and 2.7 are supported as well. Currently, Python 3.0 is unsupported.

TACTIC Python Supporting Modules

The installation of core Python is not enough for the successful installation of TACTIC. Several modules must be installed. These modules provide the following functions:

  • Extensive XML support

  • Connectivity to DB co-service

  • Win32 support on windows

  • Cryptography support

  • JSON support

  • Imaging support

The TACTIC application can support different different Python Supporting Modules, depending on the version of TACTIC.

There are a number of variables that will affect which modules will be required to install on a host machine. These considerations are;

  • DB Co-service deployed

  • Desired support module deployed when multiple support module types exist.

Support Module Type Module name TACTIC supported version
XML support lxml All
DB Co-Service Support Psycopg2 or CX-Oracle (psycopg2 is preferred for postgres database set-up) All
Win32 (used in client computers interacting with the server) PyWin32 All
Cryptography PyCrypto All
JSON (not needed since Python 2.6) SimpleJSON All
Imaging PIL and ImageMagick (optional) All

Installation on Windows

On Windows systems, TACTIC Python and supporting module availability is through the websites of the supporting module projects. Additionally, Southpaw Technology supports redistribution of installers for these modules on the support web site.

Installation on UNIX/Linux

On UNIX/Linux systems, the system package manager typically has options for installing all the required Python packages onto the UNIX host machine. To find the official distribution of a supporting package, the search functionality of a package manager is useful.
