42.4. Sharing Data
The global dictionary
SD is available to store private data between repeated calls to the same function. The global dictionary
GD is public data, that is available to all Python functions within a session; use with care.
Each function gets its own execution environment in the Python interpreter, so that global data and function arguments from
myfunc are not available to
myfunc2. The exception is the data in the
GD dictionary, as mentioned above.
