When you code in other languages, you will sometimes create a block scope, like this:
statement ... statement { statement ... statement } statement ... statement One purpose (of many) is to improve code readability: to show that certain statements form a logical unit or that certain local variables are used only in that block.
Is there an idiomatic way of doing the same thing in Python?

Block Level Scope: This scope restricts the variable that is declared inside a specific block, from access by the outside of the block. The let & const keyword facilitates the variables to be block scoped. In order to access the variables of that specific block, we need to create an object for it.
What is Variable Scope in Python? In programming languages, variables need to be defined before using them. These variables can only be accessed in the area where they are defined, this is called scope. You can think of this as a block where you can access variables.
You will learn about the four different scopes with the help of examples: local, enclosing, global, and built-in. These scopes together form the basis for the LEGB rule used by the Python interpreter when working with variables.
PythonServer Side ProgrammingProgramming. All variables in a program may not be accessible at all locations in that program. This depends on where you have declared a variable. The scope of a variable determines the portion of the program where you can access a particular identifier.
No, there is no language support for creating block scope.
The following constructs create scope:
