As shown in the following figure, the same object name can be present in multiple namespaces as isolation between the same name is maintained by their namespace.
Note that the line “count = count +1” references the global variable and therefore uses the global variable, but compare this to the same line written “count = 1”. Then the line “global count” is absolutely needed according to scope rules.
one cannot access any particular object from anywhere from the code, the accessing has to be allowed by the scope of the object.
When Python interpreter runs solely without any user-defined modules, methods, classes, etc. Some functions like print(), id() are always present, these are built-in namespaces.
