    • Scope refers to the availability and accessibility of an object in the code Or you can say accessibility and the lifetime of a variable.

Types

  • Local
    • The variables declared inside a loop, and the function body are called local variables. And accessible only within that function or loop.
    • This variable is present in the local space and not in the global space.
    • Example
def print_message():
    name = 'TheProgrammingPortal'
    print('Inside Local Scope:' + str(name))
 
print_message()
  • Global
    • Variables declared outside a function or in global space are called global variables
    • These variables can be accessed by any function in the program that is, both inside and outside of each function.
    • Example
name = 'TheProgrammingPortal'
def print_message():
    print('Reading From Global Scope:' + str(name))
