![None Propagation in Python Chained Attribute Access [Duplicate]](https://docuprint.cloud68.co/uploads/none-propagation-in-python-chained-attribute-access_1200.jpg)
Is there a null propagation operator ("null-aware member access" operator) in Python so I could write something like
var = object?.children?.grandchildren?.property
as in C#, VB.NET and TypeScript, instead of
var = None if not myobject\
or not myobject.children\
or not myobject.children.grandchildren\
else myobject.children.grandchildren.property

No. There is a PEP proposing the addition of such operators but it has not (yet) been accepted.
In particular, one of the operators proposed in PEP 505 is
The "
None-aware attribute access" operator?.("maybe dot") evaluates the complete expression if the left hand side evaluates to a value that is notNone
