Decorate a class with @kwargs to automatically destructure a dictionary argument into constructor parameters.

from mo_kwargs import kwargs @kwargs class MyClass: def __init__(self, a, b=10, c=None): self.a = a self.b = b self.c = c obj = MyClass({'a': 1, 'c': 2}) print(obj.a, obj.b, obj.c) # 1 10 2

Debug

Known issues

breakingVersion 8 introduced major changes: the default destructuring changed from 'typed' to 'explicit' mode. Existing code relying on implicit type matching may fail. Use @kwargs to opt into typed mode if needed.

fix

Add @kwargs decorator to classes that previously worked without it, or adjust parameter names to match dictionary keys exactly.

affects: >=8.0.0

gotchaThe library uses the underscore (_) to mark positional parameters. Parameters starting with underscore are not destructured from the input dict; they remain as positional arguments.

fix

Ensure that any parameter you want to receive from a dict does not start with underscore.

affects: all

deprecatedThe old pattern using 'from mo_kwargs import kwargs_decorator' is deprecated and may be removed. Use the kwargs function directly.

fix

Replace 'from mo_kwargs import kwargs_decorator' with 'from mo_kwargs import kwargs'.

affects: <8.0.0
