Namespace in Python is a system to make sure that all the names in a program are unique and can be used without any conflict.

• Namespaces are containers for mapping names to objects.

• Python uses namespaces to avoid naming conflicts and to create a unique space for each variable, function, etc.

• There are different types of namespaces in Python such as local, global, and built-in namespaces.

Scopes in Python refer to the visibility of variables within a program.

• Variables defined inside a function have local scope and are only accessible within that function.

• Global variables can be accessed from any part of the program.

• Nonlocal variables are used in nested functions to access variables from the outer function.
