The bad news is that yes, there is something "like this" in Python.

The good news is that I won't tell you more about it, since it's a very
bad practice(tm). The good practice is to put your vars in a dict.

 env = os.environ

Now you just have to look at env['MY_ENV_VAR'] !-)

What do you mean "of the appropriate type" ? You want to typecast (eg.
from string to numeric) ? Then you need to know what env var must be
casted to what type ? Then you don't need to create variables 'on the fly' ?

I must have missed something...
