Behavior Change: Removed support for two-argument form of TypeGuard
including support for "type asserts". The feedback on this idea was relatively negative.
Enhancement: Added provisional support for a proposed StrictTypeGuard
feature. For details, refer to this discussion.
Enhancement: Added support for old-style (pre-await) coroutines.
Bug Fix: Fixed a bug that resulted in a false positive in cases involving bidirectional type inference with an expected callable type where one or more of the parameter types was a tuple with non-literal element types and the provided argument was a tuple with a literal value.
Bug Fix: Improved limit check for literal math.
Enhancement: Updated typeshed stubs to the latest.
Bug Fix: Fixed bug that results in false positive when using a super().__init__
call within a metaclass __init__
method.
Bug Fix: Fixed bug that results in a false positive error when using yield
within the outermost iterator of a list comprehension.
Bug Fix: Fixed a bug that resulted in a false positive when importing OrderedDict
from typing_extensions
. Added a mechanism for loading typeshed modules on demand within the type evaluator, including collections/__init__.pyi
which declares the real OrderedDict
class.
Enhancement: Added improved checks for size mismatches when unpacking known-length iterables into a list target (like [a, b] = (1, 2, 3)
).
Behavior Change: Changed the setdefault
method generated for TypedDict classes so it accepts only literal key values. Fixed a bug in the get
method generated for TypedDict classes so it accepts arbitrary values for the default value parameter.
Bug Fix: Fixed bug that resulted in incorrect type evaluation when using a generic type alias that consists of a union of multiple type variables that are filled with the same type when the type alias is specialized.
Behavior Change: Modified the reportMissingSuperCall
diagnostic based on feedback. It now emits an error for classes that include an __init__
and don't call through to super().__init__
even if that class derives from object
, unless it's marked @final
.
