Subject: [Chennaipy] PythonExpress for school students
Message-ID: <CAHX9ajQbxkaHVkQ5WZiahzbrehwxx8v4NQL68VJjL0sRzjSXrQ@mail.gmail.com>

Hi All,

During PyCon India 2016 open space, we discussed about conducting workshops
for school students.
Teaching school students might be a bit challenging as they have minimal
knowledge on programming. Real time and visual results will excite them to
learn programming language and try things on their own.

We can conduct python workshops with the help of low cost single board
computers like Raspberry Pi, Arduino, ExpEYES or something similar to it
which will be helpful in teaching and also make the students understand.

Since the cost of these single board computers are less, its affordable for
students to buy on their own to pursue it further.

I would request everyone to share your thoughts on the same and help in
building the workshop topics and content for school students.

Thanks,
Vijay

Message-ID: <CAHX9ajT3C-f4sVPUyYN4D+TOhx2xGmSVwq_wetq+5GmuRPNG8w@mail.gmail.com>

Hi All,

Last 2 months were wonderful, conducting workshops all over India for
almost free of cost.

We have 12 upcoming workshops and looking forward to conduct more workshops
and spread love of Python. Kudos to all tutors and volunteers without whom
this would not have been possible.
We have reached out to 11 states and 135 colleges, there are lot more
colleges and students we have to reach out to.

Request everyone to help us connect to more colleges. You can talk to your
college and the colleges you have contact with and tell them how Python is
useful in your day to day work and how important it will be for students to
learn Python.

Workshops are for free of cost, we only look for Tutor's travel expense
from college in case Tutor has to travel to a remote location.

In case of any queries, please do drop mail to '*contact at pythonexpress
dot in'*.

Thanks,
Vijay

For the visual part, the workshops could use python's turtle graphics
module. It works directly from the REPL and pretty fun to play with.

But if the goal is to teach the core parts of python, maybe a visualizer
(like the one at pythontutor.com) could help visualize the control flow?

Hey there,

Title: "Demystifying how imports work in Python"

Talk Description:

It just so happens python abstracts away the inner workings of import statement beautifully. But are we aware of how python behaves when it encounters an import statement for a module? Better yet what is a module actually? Packages anybody?

How would  different import styles compare with each other. Any Best practices when importing modules. What about that __init__.py you saw the last time you read someone else's code.

Best,

Message-ID: <CAGO4j2=nnxc3oR+YwXBYxk9rFVgjvUGzNYTP74ZoOs0qqZA=Tg@mail.gmail.com>

Hi all,

While all of us are waiting for next year's PyCon India, a group of Python
community members decided to meet at the beginning of the year  :)
It quickly became apparent this should also be open to the community.
Therefore, another 4 days of PyCon will be held in Pune during
February, 16-19th, 2017 so the Indian Python Community and friends can meet
again during spring. :)

There will be 2 days of talks, and 2 days of devsprints. While the details
are still being finalized, the call for
volunteers is open. PyCon is a community conference and run by volunteers.
If you think you will
able to help out in some ways, feel free to submit your contact details in
the following form [1]. The
organizing team is being formed from volunteers as well and will make sure
everyone is contacted back.

There will be opportunities to join in as on-site volunteers, but this mail
is going out early to give everyone
a chance to make a successful PyCon for the community.

Colonel Sir,

I suggest you come and attend the Chennaipy meetup scheduled this Saturday
at Institute of Mathematical Sciences @3pm. I presume you have not attended
the Python meetup earlier. Python meetups are where python professionals,
enthusiasts and starters (in general, pythonistas) meet, talk and listen
about python language, tools and techniques. If you attend the meetup, you
will understand what Chennaipy does and probably get some idea / fine tune
your idea of a similar group.

Moreover, you can present your idea during the Networking session and get
inputs from Pythonistas in a face to face discussion as they would better
understand what your exact requirement is and may advise your accordingly.

Please check out this link and RSVP to the meetup. You can get the exact
location and more information on the below link.

https://www.meetup.com/Chennaipy/events/234639862/

I know that I have not given you a direct answer but, I am sure this whole
arrangement will help you get a better idea of your idea.

Expecting you at the meetup.

Thanks
Azeez

Hello,

Please find the minutes of October 2016 Chennaipy Meetup

Dictionary
Dictionaries are actually lists with keys as index. A dictionary internally is a hash table (in the memory) and has an Index, hash, key, value.

Initially there are fixed slots assigned to a dictionary hash table (starts with 8). A hash function returns integer which is passed to a bits function to get index of slot.?

Collision occurs when a two distinct keys get the same hash. There are back up slots to avoid collisions and this is done with the help of a pseudo random probing algorithm. The order of insertion gets changed while retrieving in dictionaries because of collisions. Reading value also uses pseudo random algorithm to prevent collision.

Deleting a key will replace with a dummy key. This is to help in collisions. Since inserting key changes order, python doesn't allow inserting during iteration.

The Probing algorithm is optimised and super fast and it trades spaces (memory) for speed. So If there is a need to conserve space, use tuple.

We can?t use mutable keys since python uses hashes for keys and changing the key will break the hash.

Modules
Any python source file is a module. To check where a module resides, use inspect.getfile. All the statements in a module get executed from top to bottom.

Packages are used to organise large number of modules in a systematic manner.?

The command import * brings all but it is not a good practice as it pollutes the namespace. We need to be consistent with import style. There is no improvement in performance on importing whole file or only one function in a module.

Naming rules: Don't start with integer, don't use system package names, no non ASCII chars in file names.

The import command searches from directories present in sys.path. The modules get imported only once. To force reload a module you can use "from importlib import reload?. This is not recommended in production code.

Use explicit relative imports (from . Import foo) to minimise breaking on package name change. The init.py file brings submodules into a package

Testing
Selenium is a browser automation tool. It makes cross browser testing easy. Saves a lot! The main components are ide, RC, web driver /selenium 2, grid

Lightning Talks
Mind map experience with python and advantages of elpy (saves a lot of time). Talks on whether Indian software industry will die or not, talent pyramid, the need to stay relevant and focus on disruptive technologies like data sciences. Python fits everywhere.

Kind regards,
Bharath
