Collects implementations based on the function name. Ignores namespaces. If ambiguous type signatures occur a warning is raised when the function is defined suggesting the additional method to break the ambiguity. Examples -------- >>> from sympy.multipledispatch import dispatch >>> @dispatch(int) ... def f(x): ... return x + 1 >>> @dispatch(float) ... def f(x): # noqa: F811 ... return x - 1 >>> f(3) 4 >>> f(3.0) 2.0 Specify an isolated namespace with the namespace keyword argument >>> my_namespace = dict() >>> @dispatch(int, namespace=my_namespace) ... def foo(x): ... return x + 1 Dispatch on instance methods within classes >>> class MyClass(object): ... @dispatch(list) ... def __init__(self, data): ... self.data = data ... @dispatch(int) ... def __init__(self, datum): # noqa: F811 ... self.data = [datum] csX|j}t|r(tjj|t|}n|kr._)tuple)r r rrrrrdispatch s,rcCst|}|jdddk S)z Is func a method? Note that this has to work as the method is defined but before the class is defined.
