Chapter 1. Introduction

The Python package allows users of SpecTcl to execute python scripts within the SpecTcl program. The package provides commands to execute python scripts from file or inline with other Tcl commands. The package also provides Python-esque wrappings of the major SpecTcl objects, allowing you to manipulate spectra, parameters, gates, and variables directly from your python scripts.

Incorporating the Python package in your SpecTcl run is as simple as adding the line:

package require python
                

Note that this both adds the python command to your SpecTcl Tcl interpreter and imports the spectcl Python package into the python interpreter that runs that command. Since the same interpreter is used to run all Python commands, packages, variables, objects created in one script are fully available to subsequent scripts.
