NumPy arrays have this awesome feature, where array == 3 does an element-wise comparison and returns a list. For example:
np.array([1,2,3,4,5])==3
returns
[False,False,True,False,False]
It would be cool if Python had similar functionality for lists.
If that is not possible, perhaps we could consider allowing developers to overload operators on built-in types within the context of a project or module. For example, an overload in one module would have no effect on the same operator in a different module (such as any Python standard modules.) Additionally, let's then give the developers the option to explicitly import an overload from other modules. So, people could develop a module with the purpose of providing overloads that make complete sense within a certain context. -------------- next part -------------- An HTML attachment was scrubbed...
