You can also see that there was no previous binding for spam before the global assignment. You might have noticed that methods like insert, remove or sort that only modify the list have no return value printed – they return the default None. This is the first of two articles introducing Kvaser CANlib SDK and the Python package canlib. Sphinx adds a standard framework of useful extra roles and directives (and many optional extensions) that make it well suited to documenting Python code (and perhaps C++ if you're adventurous: see Breathe). I'm not a very prolific programmer though. It supports IPv4 and IPv6, specified via the Python documentation can come in many forms, from inline comments and docstrings within the code itself, to external documentation like user manuals and API references. There will still be one thread per CAN bus but the user application will execute entirely in the event loop, allowing simpler concurrency without Plugin Interface¶. First, let’s see how to create and send a simple text message (both the text content and the addresses may contain unicode characters): CHAPTER TWO CONFIGURATION UsuallythislibraryisusedwithaparticularCANinterface,thiscanbespecifiedincode,readfromconfigurationfiles orenvironmentvariables. 254:5000 or rfc2217://192.
