A Signature object represents the call signature of a function and its return annotation. For each parameter accepted by the function it stores a Parameter object in its parameters collection. The optional parameters argument is a sequence of Parameter objects, which is validated to check that there...
The function returnsTrueif the object is an instance of the given type. Otherwise, it returnsFalse. Here’s an example of using theisinstance()function to check if a string is an instance of theIterableclass: fromcollections.abcimportIterablemy_string="Nathan"is_iterable=isinstance(my_string,It...
