PyCon AU 2013
The dates for PyCon AU 2013 have been set: July 6 – 7, 2013, which will coincide with uni holidays. There is a plan for miniconfs, such as Django and OpenStack, on the 5th, hopefully with another CodeWars, and then sprints on the 8th and 9th.
The parse module
Richard Jones briefly covered the syntax for new style string formatting before launching into
parse(), which is essentially the inverse of
format(): parsing strings with format() syntax. There are 20+ types/conversions available and a plugin system to add your own types.
There are additional (obviously named) functions:
compile(), and while this may seem very reminiscent of
re, the regular expression module, it offers a lot of the power without the often accompanying complexity.
Richard also presented his PyCon AU 2012 talk on message queueing by an MQ noob, covering some of the popular MQ solutions, with a focus on RabbitMQ and Pika. The summary was that RabbitMQ (and AMQP) is enormously powerful but also challenging to configure and debug, especially if you do not know Erlang (which RabbitMQ is written in).
TCPCatcher was mentioned as a useful tool for testing networks. It is cross-platform and allows you to monitor, record and modify TCP packets.
I recommend checking out Richard’s slides.
- Syntax for delegating to a subgenerator, as per PEP 380
- Explicit unicode literals, to simplify porting legacy 2.x code
- Flexible unicode representation
- Reworked I/O exceptions
- A script launcher for MS Windows
- Removal of a GIL (but this is not the GIL you were looking for…), the Global Import Lock
- Tracebacks on segfault
- Easy namespace packages
- virtualenv support in core, via PEP 405
- A new type: types.SimpleNameSpace
Could 3.3 be the release that is the tipping point for the adoption of Python 3?
Despite the public holiday for a horse race, we will still be meeting on November 5, the usual first Monday in the month.
