one option is to make your .txt file a .py file, and say 'import 
filename' (without the .py) in your app - that results in executing the 
commands in that file, immediately.

if you need more control over when the commands are executed, you can 
make them functions in the .py file, and then call those (e.g. say def 
drawrect(): glBegin ... in your commands.py, and then do: import 
commands; commands.drawrect() in your app).

there are also tools like the eval() function for which you can give 
commands as strings for python to execute, but i think you are better 
off with by making .py files (i.e. python modules) that you can import 
and use.

if you have a running application, where want to load commands from a 
file on the fly, you can use the reload() function to re-import a module 
(the modified .py file). see the documentation for more info.
