[issue32135] Dict creation with update will result to NoneType

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

The update() method returns None. This is a correct behavior.

The rationale is the same as for list.sort(), see 
https://docs.python.org/3/faq/design.html#why-doesn-t-list-sort-return-the-sorted-list.

[issue32135] Dict creation with update will result to NoneType

[Eric V. Smith]

Eric V. Smith  added the comment:

dict.update() returns None, so this is expected. Maybe you want:

>>> x = {"X":123}
>>> x.update({"abc":123})
>>> x
{'X': 123, 'abc': 123}
>>>
