Chennaipy April Meet Minutes
Chennaipy met again on the 28th of April. This time around we had
about 10 people.
B.R.E.A.K
=== Python Lists
Since there were quite a few newbies, the meeting started off with a
short introduction about Python. This was followed by the Python Lists
talk by Deepan. He showed the following list operations:
1. List creation.
2. Accessing list elements.
3. Addition of list.
4. Scalar multiplication.
5. List comprehension.
=== Python Dictionaries
The next talk was on Python Dictionaries by Rengaraj. He describe how
data is stored in the dictionary as key-value pairs. He then showed
the following dictionary operations:
1. Dictionary creation.
2. Accessing dictionary elements.
He then demonstrated dictionaries using an example of counting the
occurrence of letters in a string.
=== MVC Design Pattern
The next talk was on the MVC Design Pattern by Vijay Kumar. Vijay
Kumar first described, the importance of design patterns. He then
explained a variant of the MVC design pattern. The variant he
described was based on MVC pattern used in Apples' Cocoa framework. He
demonstrated the MVC design pattern using an address book example. The
address book had a form based view written in wxPython. An XML file,
parsed into a ElementTree, is used as the model. A control helps to
interface between the View and the Model. He also described the
advantages of the MVC - like ease of testing, increased orthogonality,
and ease of remoting the controller in the future.
A follow up article based on the talk is available at
http://www.zilogic.com/blog/tutorial-mvc.html
=== Video
We had planned for a Pycon video, but Jagadish suggested a YouTube
video on the MVC design pattern. We went in for a quick vote after
playing both the videos for a minute. People voted for the video on
the MVC design pattern. So we went on to play it. The video
demonstrated another variant of the MVC design pattern, using Qt.
