Python Scope

Python Scope

• The place where a variable is created defines its availability to be accessed and manipulated by the rest of the code. This is known as scope.

There are two types of scope:    

1. Local Scope

2. Global Scope

1. Local Scope 

• When you declare a variable inside a function it only exists inside that function and can't be accessed from the outside.

• The variable name was declared inside the function, the output is the same as before:
• But this will throw an error.

2. Global Scope

• A global scope allows you to use the variable anywhere in your program.
• If you variable is outside a function, it has global scope by default.

Note : That the function could use the variable name and print my name is Programmerfect.

Mixing Scopes

• If you use the same name of variables inside and outside a function, the function will use the one inside its scope.
• So when you call print_name(), the name="Programmerfect" is used to print the phrase.
• On the other hand, When calling print() outside the function scope, name="Richard Rahul" is used because of its global scope.
