Global variables refer to any variables declared at the top level of a Python module. That makes them accessible throughout the module‘s global Python scope. For example: top_menu = "File, Tools, Help" # global variable. def menu_handler(): print(top_menu) # accessing global. menu_handler() Here top_menu is a global variable that we then ...
