"""
Change the global/default scope instance by Python `with` statement. All
variable in runtime will assigned to the new scope.
This function switches scope through python `with` statement.
Scope records the mapping between variable names and variables ( :ref:`api_guide_Variable` ),
similar to brackets in programming languages.
If this function is not invoked, all variables and variable names are recorded in the default global scope.
When users need to create variables with the same name,
they need to switch scopes through this function
if they do not want the mapping of variables with the same name to be overwritten.
After switching through the `with` statement,
all variables created in the `with` block will be assigned to a new scope.
Parameters:
scope: The new scope.
Arg
s:
scope: The new global/default scope.
Return
s:
None
Examples:
.. code-block:: python
