This is the default property of python to return multiple values/variables which is not available in many other programming languages like C++ or Java. Second, code the simplest possible Pair class, or use an array. To do so, return a data structure that contains multiple values, like a list containing the number of miles to run each week. But, if you do need to return a pair, consider what concept it represents (starting with its field names, then class name) - and whether it plays a larger role than you thought, and if it would help your overall design to have an explicit abstraction for it. Luckily, there are several workarounds in C to return multiple values. Likewise, arrays also can be passed to the method and returned from the method.
