Python, Step by Step vs Kototap

A quiz-based Python learning app, sized for your phone. Python, Step by Step is a Python intro built for people learning to code for the first time. Tap-only micro-lessons that take a few minutes each cover the basics — variables, data types, branching, loops, functions — without ever asking you to type a single line of code. Highlights - A few minutes per lesson. Built for your commute, your coffee break, your before-bed reading - 16 units — from the basics all the way to classes, exceptions, and the standard library - Varied exercises — predicting output, filling in blanks, reordering lines, and more - All learning content is free. No paywalls - Streaks (consecutive days) help you build the habit Who it's for - People just starting with programming - Anyone who needs to pick up Python for work or a career switch - Anyone who wants to touch a bit of code in short bursts What you'll learn (16 units) 1. Welcome (first program, print, comments, input) 2. Variables and Data Types (numbers, strings, booleans) 3. Doing Math (operators, f-strings) 4. Branching (if / elif / else, logical operators) 5. Repeating (for / while, break / continue) 6. Functions (defining, arguments, return) 7. Talk to your program (input, prompts, interactive programs) 8. Group with lists (create, index, loop) 9. Dictionaries and tuples (keys and values, sets) 10. Classes 101 (__init__, self, methods) 11. Exceptions (try / except, raise) 12. Files (open, read, write) 13. Functions, leveled up (lambda, *args, map / filter) 14. Class inheritance (super, overriding) 15. Comprehensions and iterators (generators, yield) 16. Standard library (math, random, datetime, os)

Kototap weaves spaced repetition into stories. Words and grammar are best learned in context, inside sentences doing real work, so that's where your reviews live. Tap a word you don't know, and it comes back in your next stories — until it sticks. Tap a word to add it to your deck • Instant, in-context explanations as you read • Every word you look up joins your deck automatically Words resurface until they stick • Spaced repetition schedules each word's return inside future stories • Watch words climb from Learning → Familiar → Comfortable, story by story Grammar gets the same treatment • Grammar patterns (〜てしまう, 〜そうだ, …) are tapped, tracked, and resurfaced just like vocabulary • One system for everything you're learning — no separate grammar study Stories always at your level • Short, engaging stories generated for you — tuned so you understand about 90% on sight • Twelve difficulty steps from N5 to N2; climb one step at a time • Made for the intermediate plateau — you know a lot of words, but native material still buries you Reading that stays fun • Story decisions let you choose where each story goes next • Listen along with built-in audio narration Spaced repetition, in context — the way words and grammar actually stick.
