The 'global' statement declares a name to be module-level, so there's no reason to use it at the top level of either a script or a module, since everything there is module-level anyway. You only need it if you want to assign to a module-level name from within a function, e.g. spam = 17 def f(): global spam spam = 42 f() # spam is now 42 A script is a module, so everything that applies to modules also applies to scripts. -- Greg -- https://urldefense.us/v3/__https://mail.python.org/mailman/listinfo/python-list__;!!G_uCfscf7eWS!airWCCS1QeLAhk0AfN3VxhuV9MZkx80000YBhs5Vjf89K2WZPjhCUkXt9culFzwlX1_ON0G17lukcR79-kWAsA$ -- https://mail.python.org/mailman/listinfo/python-list
