Overview

As much as this series is to educate aspiring computer programmers and data scientists of all ages and all backgrounds, it is also a reminder to myself. After playing with computers and numbers for nearly 4 decades, I've also made this to keep in mind how to have fun with computers and maths.

Using Jupyter notebooks as an interactive learning medium, this series provides an introduction to:

  • Computer Science
  • Python programming language
  • Numerical computing
  • Numbers theory
  • Prime numbers
  • Data visualization
  • Deep learning

Part 1 : Introduction

Start learning here or

Binder

What you will learn:

  • print is the command to print something on the screen
  • Math operations are very easy to perform in Python
  • Python deals with numbers based on data types
  • In Python there are two numerical data types; int and float
  • Functions are powerful tools to easily perform various operations
  • Functions may accept arguments (parameters) as input
  • Functions are computer processes, and arguments are what is being processed
  • It's very easy to create your own functions

Part 2 : Prime Numbers

Continue learning here.

Binder

What you will learn:

  • Prime numbers relate with divisibility
  • Divisibility means that when one number is divided by other, the product is not a whole number
  • A prime number is any number that is divisible only by itself and 1
  • Binary means 0 and 1
  • Boolean logic is the binary language of computers
  • Python gives us an easy to use way to instruct computers
  • Boolean logic statements involve is, is not, and and or statements
  • Boolean statements can be joined together
  • Boolean statements always return either True or False as output
  • It's easy to perform computing operations with small numbers
  • The biggest prime number is a really big number
  • Very big numbers require vast networks of computers joined together

Part 3 : Algorithms Overview

Continue learning here.

Binder

What you will learn:

  • Algoritms are like insides of factories
  • Algoritms process inputs to produce outputs
  • Conditional statements are a tool for putting boolean logic in to action
  • Conditional statements are part of "flow control"
  • Flow controls give us the ability to create rules for computer programs
  • The three conditional statements in Python are if, else and elif
  • Even just if alone can be used to create a conditional statement

Part 4: Automation Overview

Continue learning here.

Binder

What you will learn:

  • Generally speaking computer programs are focused on process automation
  • Loops are a highly effective method for automation
  • With small changes to our code, we can make big improvements in capability
  • Sometimes we can get more done with less code!
  • It's very convinient to store values in to memory
  • Computer memory is nothing like human memory, and also not like a safe deposit box
  • Any value can be stored in to memory
  • Numbers can be automatically generated with range function
  • It's meaningful to learn new concepts by gradually improving things

    I'm one of the founders of open collective. We love your mission and we'd like to share your collective on our newsletter coming out today (sorry for the short notice). I'd be great if you can add some more information, a logo (maybe @mikkokotila you can add an avatar to your profile?) You can also edit your goals in opencollective.com/jupyter4kids/edit Let me know if I can help in any way, I'd love for your mission to succeed!

    Activating Open Collective

    Hi, I'm making updates for Open Collective. Either you or a supporter signed this repo up for Open Collective. This pull request adds backers and sponsors from your Open Collective https://opencollective.com/jupyter4kids ❤️

    It adds two badges at the top to show the latest number of backers and sponsors. It also adds placeholders so that the avatar/logo of new backers/sponsors can automatically be shown without having to update your README.md. [more info]. See how it looks on this repo. You can also add a "Donate" button to your website and automatically show your backers and sponsors there with our widgets. Have a look here: https://opencollective.com/widgets

    P.S: As with any pull request, feel free to comment or suggest changes. The only thing "required" are the placeholders on the README because we believe it's important to acknowledge the people in your community that are contributing (financially or with code!).

    Thank you for your great contribution to the open source community. You are awesome! 🙌 And welcome to the open collective community! 😊

    Come chat with us in the #opensource channel on https://slack.opencollective.com - great place to ask questions and share best practices with other open source sustainers!

    Notebook 3 had mixed print statements for Py2 & 3, changed all to Py3.

    My first pull so hope I'm doing this right, there are lots of edits in the comparison that I don't understand, its confusing considering I just added brackets in a few places... Wondering if its due to copies or something about underlying code, any help with my understanding greatly appreciated

  • Use == instead of 'is' for comparing number

    Use == instead of 'is' for comparing number

    Hi,

    In this notebook: https://github.com/mikkokotila/jupyter4kids/blob/master/notebooks/numerical-computing-is-fun-2.ipynb you use the 'is' keyword to compare numbers.

    This should be avoided, because Python's semantic does not guarantee that '1 is 1'. In fact, in the CPython implementation, this is only True for integers lower or equal to 256:

    >>> a = 257
>>> b = 257
>>> a is b
False
>>> a = 256
>>> b = 256
>>> a is b
True

    README Brazilian portuguese translation

    This project is very interesting and I believe that it can be a motivation for brazilian students. I think that more contributions can be added if more people could understand the texts. So I propose to translate content to brazilian portuguese as it be published and suggest changes according brazilian speakers use it.

Here I tried a small fun project using python OpenCV, mediapipe, and pydirectinput. Here we can control moves car game when yellow color come to right box (press key 'd') left box (press key 'a') left hand when thumb finger open (press key 'w') right hand when thumb finger open (press key 's') This can be improved later by: Improving press left and right to make them More realistic. Fixing some bugs in hand tracking.
