Free, in your browser, every step checked by the simulator. Chapter 1 project ### Classes Classes and objects on a BME280: the driver class you already use, a Reading class of your own with methods and __str__, an object that remembers the highest temperature, and inheritance. Open it in the simulator Chapter 2 project ### Files and logging Write a knob's readings to a file and read them back, a CSV any spreadsheet opens, the logging module with its levels in place of print, and a log file: what the Pi's engine supports, and what lasts. Open it in the simulator Chapter 3 project ### Generators yield and next, a generator that streams knob readings forever, a moving average built as a pipeline of generators, islice to take just a few, and generator expressions. Open it in the simulator The map ## Chapter by chapter Each lesson opens when the one before it is done, and each chapter ends in a project. Chapter 1 ## Structure Split code into modules, and bundle data with its functions in classes. Open 265 XP ### Modules Split a program into files: the OLED driver you have been importing all along, the standard library, a module of your own in a new tab, and what __name__ == "__main__" is for. 0 of 6 steps Start What is in it Project Locked 530 XP ### Classes Classes and objects on a BME280: the driver class you already use, a Reading class of your own with methods and __str__, an object that remembers the highest temperature, and inheritance. 0 of 6 steps Chapter 2 ## When things go wrong Exceptions, files and logs: code that survives a loose wire and tells you what happened. Locked 265 XP ### Exceptions Read a traceback, catch the I2C error a missing chip really raises, scan two addresses without crashing, raise an exception of your own, and clean up with else and finally. 0 of 6 steps Project Locked 530 XP ### Files and logging Write a knob's readings to a file and read them back, a CSV any spreadsheet opens, the logging module with its levels in place of print, and a log file: what the Pi's engine supports, and what lasts. 0 of 6 steps Chapter 3 ## Craft Tests with assert, and generators that stream data forever. Locked 265 XP ### Tests with assert No pip and no pytest, so tests are plain assert: catch a real off-by-one in a voltage conversion, test the edges, write a ten-line test runner, and let a failing test drive a fix. 0 of 6 steps Project Locked 530 XP ### Generators yield and next, a generator that streams knob readings forever, a moving average built as a pipeline of generators, islice to take just a few, and generator expressions. 0 of 6 steps Chapter 4 ## Boss project A sensor logger with a screen, a CSV and a log, built from every habit in the course. Locked 303 XP ### Project: a sensor logger The boss project: a BME280 and an OLED on one I2C bus, a logger module with a Sample class and a generator of samples, a test before anything is trusted, a CSV log, the latest reading on the screen and a warning when it gets hot. 0 of 7 steps Syllabus ## Every lesson in the course All 7 lessons, in order, each with what it covers. Any of them opens in the editor right away. Chapter 1 ### Structure - Modules Split a program into files: the OLED driver you have been importing all along, the standard library, a module of your own in a new tab, and what __name__ == "__main__" is for. - Classes Classes and objects on a BME280: the driver class you already use, a Reading class of your own with methods and __str__, an object that remembers the highest temperature, and inheritance. Chapter 2 ### When things go wrong - Exceptions Read a traceback, catch the I2C error a missing chip really raises, scan two addresses without crashing, raise an exception of your own, and clean up with else and finally. - Files and logging Write a knob's readings to a file and read them back, a CSV any spreadsheet opens, the logging module with its levels in place of print, and a log file: what the Pi's engine supports, and what lasts. Chapter 3 ### Craft - Tests with assert No pip and no pytest, so tests are plain assert: catch a real off-by-one in a voltage conversion, test the edges, write a ten-line test runner, and let a failing test drive a fix. - Generators yield and next, a generator that streams knob readings forever, a moving average built as a pipeline of generators, islice to take just a few, and generator expressions. Chapter 4 ### Boss project - Project: a sensor logger The boss project: a BME280 and an OLED on one I2C bus, a logger module with a Sample class and a generator of samples, a test before anything is trusted, a CSV log, the latest reading on the screen and a warning when it gets hot. Keep going ## The next course on your track Python with real habits is part of the coding track, a ladder of courses from zero to expert. Next course ### Data structures and algorithms The ideas every programmer is asked about, built and measured on an Uno: big O, linked lists, stacks and queues, hash maps, sorting and binary search. Ends with a leaderboard that needs them all. Open the next course Track ### Coding track Python and C++ from your first print to classes, tests and state machines. Every program runs on a simulated board, so a bug is something you can see. See every course on the track Kits ## Build it on your bench too Every lesson runs in the simulator with nothing to buy. When you want the real thing, these kits have the parts. Have a kit already? ### Find your kit Pick the starter kit you own and run every lesson in its manual with the same parts on the same pins. See every kit Questions ## About Python with real habits Is Python with real habits free? Yes. All 7 lessons of Python with real habits are free and run in your browser, with nothing to install and no parts to buy before you start. Do I need a real Raspberry Pi 4 Model B? No. Every lesson runs on a simulated Raspberry Pi 4 Model B with its parts on the canvas, and the simulator checks each step as you go. When you want to build it for real, the same wiring and code work on a real board. How long does Python with real habits take? About 6 hours: 7 lessons in 4 chapters, each one a few short steps. Your progress is kept, so you can stop after any lesson and pick up where you left off. What will I build? Each chapter ends in a project that puts it together: Classes, Files and logging and Generators. Where do I start? With "Modules", and each lesson builds on the one before it. New to circuits? Electronics basics is the course that starts from zero.
