== Talk 1 on Mining Twitter with python by Dorai Thodla
Dorai Thodla gave a nice presentation on Mining Twitter. He explained
about the use of Twitter nowadays. He explained the twitter as real
time news provider with various examples. Then he showed Twitter app
written in python, through which he explained how he bookmarks links
posted on Twitter.
Dorai showed a code for reading twitter feeds and saving that in a
database. Using sql database command he converted those tables in to
== Talk 2 on Hacking python: Adding New python statement by Vijay.
Vijay gave a session on `turtle` a game programing language for
teaching programing in school level.He also told that he learned
programing using logo. He believes that teaching programing using
turtle will actually create interest among students in programing
irrespective of the programing language.
In logo for iterative statement they use `repeat`. But in python we
don't have repeat for iteration. we have `for` or `while` for
looping. Vijay wants to solve this problem by hacking python.
He showed three ways to use repeat in python script so that
interpreter wont through error.
=== 1st way
He used a shell script to change the repeat function in to for loop and
give a new file output.py in which
repeat 4: ---------> for i in range(4):
fd(2) convert.sh fd(2)
=== 2nd way
The draw back of above code is the repeat statement have any space,
conversion wont work.
So he come up with new idea where he used python script as a
conversion script. He used token module to replace the `repeat` with
`for` tokens in order to solve if repeat statement varies with space.
=== 3rd way
Now vijay dont want a conversion script to do the job, he want a
python script in which repeat statement is used should be combined
directly by python.
He used encoding technique to solve the problem. He wrote own
encoding `pyturtle.py` to convert tokens in to statements. To
initialise that, he copied the file to python site packages folder.
This month python meet end up with a good note and with two good talk.
We will see next meet with few more talks.
