Built-In and Global Scopes
As mentioned earlier, the global scope is your code's main scope (environment). Every script (.py file) has its global scope.
1234567first = "This" second = "is" third = "the" fourth = "main" fifth = "scope" print(first, second, third, fourth, fifth)
Note
There is only the built-in scope out of the global scope.
We can use functionality from outer scopes in inner scopes. This means that we can use built-in functionality in the global scope as well as in local scopes, which are nested within the global scope.
Look at the example:
12345678print(len("some string")) # built-in objects usage number = 15 # global scope def print_number(): print(number) # global object usage print_number()
In the example above, the global variable number is used inside the print_number() function local scope.
You can access variables and functions from outer scopes but cannot change them:
1234567number = 221 def modify_global(): number += 5 modify_global() print(number)
You can access the change of a global variable/function using the global keyword:
123456789101112number = 20 print(number) def modify_global(): global number number += 10 modify_global() print(number) modify_global() print(number)
1. What scope is the main scope of your code?
2. What scope is the Python Tools scope?
