if I understand you correctly, you need to set/retrieve twill variables
from Python, and set/retrieve Python environment variables from twill.
Here are some code snippets that might help:
# set a global variable from Python using commands
# retrieve a global variable from twill in Python
globals_dict, locals_dict = twill.namespaces.get_twill_glocals()
print eval('a', globals_dict, locals_dict)
# set a global variable from Python using dictionary
globals_dict['b'] = '6'
# set an environment variable
twill.commands.run('import os; os.environ["test"] = "hello"')
# retrieve an environment variable
twill.commands.run('global x; x = os.environ.get("test")')
Note that 'twill.commands.run' can be used directly from twill, e.g.
>>> run 'global x; x = os.environ.get("test")'
>>> echo $test
