A scope is a block of code where an object in Python remains relevant.Each and every object of python functions within its respective scope.As Namespaces uniquely identify all the objects inside a program but these namespaces also have a scope defined for them where you could use their objects without any prefix. It defines the accessibility and the lifetime of a variable.

Let’s have a look on scope created as the time of code execution:

• A local scope refers to the local objects included in the current function.
• A global scope refers to the objects that are available throughout execution of the code.
• A module-level scope refers to the global objects that are associated with the current module in the program.
• An outermost scope refers to all the available built-in names callable in the program.
