[Chennaipy] Minutes of January meetup

[Abhishek Yadav]

Hello,

The meetup started with Shreyas setting the context. He gave a short
presentation on what a meet-up is, and what is it not, and what to expect.
After that we went in for the talks.

The first talk was *Environment for a Python Dev* by Dinesh Kumar
<http://www.meetup.com/Chennaipy/members/161180472/>
He talked about setting-up and using a working environment for python
development using various tools an libraries. He covered the following:
- How code with `print` could break in Python 3, *pyenv shell* can help
change python versions. And how it also helps with library dependencies.
- How provisioning tools like *Ansible* can be used along with pyenv to
help setup project dependencies.
- On how to do build and tests, and use tests as documentation
- On choices for linters and style checkers: *Pylink*, *Pep8*, *pyflakes*
- And about how to use PYVERBOSE

The second talk was on *Algorithmic analysis and Time complexity in Python*
 by Ashok Govindarajan <http://www.meetup.com/Chennaipy/members/197137280/>
This talk was about:
- Measuring the execution time of algorithms in Python - simple addition
program
- Big O Notation
- Time complexity of Python Operations.

Then we all stepped out for a coffee break.

The next talk was on *Debugging the easy way with python debugger* by Gaurav
Sehrawat <http://www.meetup.com/Chennaipy/members/73333582/>
This talk covered the essentials of using *pdb* - the Python debugger. It
went into various ways of invoking pdb, and a more sophisticated
alternative called *pdgpp*. The speaker also went into a demo of the
debugging session using an encryption program.

After that we had a few lightening talks:
1. Venkatesh talked about an attendance management system he had worked on
2. Sharmila talked about additions to environment using the Conda project.
3. Shreyas talked about tech-communitiy's behaviour towards open source
leaders.

With that, and a group photo, the meet-up came to an end.

Regards,
Abhishek
