This is a simple s-expression parser written in Python 3. It understands symbols and numbers and uses tuples to represent the data internally.

Creating tuples from generator expression is fast.

Today we're going to look at how to filter items in tree data structures using Python 3. We're going to compare a stateful approach and a functional and recursive approach. Finally, we discuss the advantages of a functional implementation.

As you might know, CPython, the most commonly used implementation of Python, uses a stack based virtual machine to run Python scripts.

This means that Python script ASTs are never directly executed. Instead, CPython compiles .py script files into byte code files first (.pyc files). This lets Python perform some optimizations during the byte code compilation step. You can then ship byte code files to end customers instead of raw scripts. This is useful to make reverse engineering hard. Ableton Live includes a CPython interpreter for its Music Instrument Digital Interface (MIDI) hardware integration. It doesn't let users look at the actual hardware integration scripts though. Instead, Ableton includes all hardware integration scripts in their compiled .pyc form.

This is a short evaluation on whether one can perform a series of basic tasks using the APIs that cloud photo services provide.

With the new async syntax in Python 3.5, defining asynchronous functions has become a lot simpler. In this article, you can see an example for this new feature.

Given a list items, that contains ints and None, produce a list that only contains the int values with their order of appearance preserved.

The other day I received this ominous message on Skype from an infected machine:
