How do I access bamboo environment secret variable inside python script?

Question

I have defined a global bamboo secret variable and I am using it inside my python script like this:

my_var = os.environ['bamboo.my_environment_secret']

It's returning None.

I have defined a global variable named my_environment_secret in Bamboo. The way this script is executed, I can't pass any parameters from command line. So it has to be accessed directly inside the script.

Since python doesn't accept '.' as  valid character in variable names, i tried replacing '.' with '_' ( underscore) and that seemed to have done the trick.
