Thankfully, there is no such thing (can you say spaghetti code?). The
closest approximation, as I said in my previous reply, is to use the
namespace of a designated module for this purpose, and import that
module wherever you need to access/modify these "superglobal"
variables.

Example:
#g.py:
#this module exists to hold superglobal vars
global1 = "foo"
global2 = "bar"


#elsewhere.py:
#this is some other module in the same program
import mypackage.g as g

print "global #1 = ", g.global1
print "global #2 =", g.global2
g.global1 = "baz" # modify a superglobal
g.global3 = "qux" # create a new superglobal


Cheers,
Chris
