Python for kids¶

This section is for young future Lino developers. You’ll probably need somebody to help you with getting started.

How to install Python on a Debian-based Linux:

$ sudo apt-get install python3 python3-tk idle3

Introduction 1 (using Turtle)¶

Download the turtle1.py script and play with it: Try to modify it and discover what happens.
More free games in Turtle : https://www.grantjenks.com/docs/freegames/
Have a look at the official turtle docs but don’t be scared if you do not understand much (these docs are not written for real beginners like you).

A “Hello world” program using tkinter: https://gitlab.com/lino-framework/book/-/tree/master/docs/dev/newbies/gui1.py

This uses the “grid” layout method. The widgets are arranged by placing them in a cell of the grid. The button spans over two cells. Numbering starts with 0 and in the top left corner.

The “number guessing game” using tkinter: https://gitlab.com/lino-framework/book/-/tree/master/docs/dev/newbies/gui2.py. Ideas for exercises: add a counter and a timer so that the winner knows how many guesses and how many seconds they needed.
See also the official tkinter docs and Frederik Lundh’s Comprehensive list of events and http://www.tutorialspoint.com/python/python_gui_programming.htm

After the introduction we invite you to follow the Python tutorial at w3schools. Read the texts and play with the code examples.

To open the “Command Line” on a Windows PC, you click the Windows button (in the lower left corner) and type “cmd” in the search field.
