ProCodeCG codeMeetUp #101 – Pawitra Studio – Python 101 – 3 April 2017

Python 101 was the topic for today’s codeMeetUp() 🙂

People should be aware of ProCodeCG Coding Mom because they’re learning everyday 🙂

Today the audience were all from Coding Mom 🙂

Pak BR gave in intro while waiting for Mas Aditia A. Pratama

PERL vs Python 😀

Mom’s started learning these hard core programming. Cannot imagine what will happen a year from now 🙂

Ok then mas Adit introduce us to Cloud 9, an online code editor

We also learned about frameworks

And how to code on cloud 🙂

It is amazing how we expand our knowledge every week, by learning a wide spectrum of topics 🙂 It was so interesting today, we forgot to take pic of the speaker and all audience 😀

What is the difference between those two? 😀

Buckle up, we’re about to find out!

Lots of questions from the audience

plus lots of lines of code

and more!

This is us!

We did screen and video recording, but it will take some time to go through some editing process. We will let you know when it is uploaded to ProCodeCG Channel on YouTube! 😉
