5 can be solved using the new methods. The last section of this chapter introduces I/O with files and URL web pages, showing how strings and dicts can be used to organize text data, and how the the pickle module can be used to serialized arbitrary Python objects into files....
And when it comes to reusing code in Python, it all starts and ends with the humblefunction. Take some lines of code, give them a name, and you’ve got a function (which can be reused). Take a collection of functions and package them as a file, and you’ve got amodule(which can...
date/period, and function types, along with tuples, arrays/lists, and dictionaries of these types. (Python functions can be converted/passed to Julia functions and vice versa!) Other types are supported via the generic PyObject type, below. ...

Here's a function that recursively adds lists, tuples and dictionaries: from ovld import ovld, recurse @ovld def add(x: list, y: list): return [recurse(a, b) for a, b in zip(x, y)] @ovld def add(x: tuple, y: tuple): return tuple(recurse(a, b) for a, b in zip(x,...
