= April Monthly Meet Minutes == 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 text document. == 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 input.py output.py ------ ---------- 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. == Conclusion This month python meet end up with a good note and with two good talk. We will see next meet with few more talks.
