There’s an abundance of third-party tools and libraries for manipulating and analyzing audio WAV files in Python. At the same time, the language ships with the little-known wave module in its standard library, offering a quick and straightforward way to read and write such files. Knowing Pyt...

The CPU is the brain of a computer, but it operates at the nanosecond timescale. Most other components of a computer are far slower than the CPU. For instance, a magnetic hard disk read takes thousands of times longer than a typical CPU operation. If a process needs to write something...

By default, the runtime expects the method to be implemented as a global method in the function_app.py file. Triggers and bindings can be declared and used in a function in a decorator based approach. They're defined in the same file, function_app.py, as the functions. As an example...
If at any moment, there is a stable Python release that is not in this list, rest assured it is being worked on and will be added. Important For Python 3.4 and only that version, we need other Python version as a compile time dependency. Nuitka itself is fully compatible with all ...
