Use a container, and change the container's contents, eg make the global
"variable" a dictionary, and access the different "global variables" via
the dictionary's keys.

What you're seeing is due to Python's variables being references to
values, rather than actual values.  With the container approach, all the
references will still point to the container, even though the contents
change.  In fact, Python itself does pretty much all name lookup through
dictionaries.
