Python Study Notes vs Python, Step by Step

Python Study Notes is a pocket reference and quiz app for learning Python, guided by two friendly characters, Chikuwa and Hanpen. REFERENCE - 117 topics covering Python grammar and popular libraries: NumPy, pandas, Matplotlib, Seaborn, scikit-learn, OpenCV, MeCab and PyTorch - Every topic explains what it is, when you'd use it, and what to watch out for, in plain words - Code examples with their real output, including the charts they draw - Short conversations between Chikuwa and Hanpen that dig into the questions beginners usually have - Tap a technical term to see a quick definition - Difficulty labels (Beginner, Intermediate, Advanced) help you decide what to read first QUIZ - 600 questions in 10 categories, each at three levels - Every answer comes with an explanation and a short dialogue - Review mistakes: questions you got wrong come back until you get them right - Your progress is saved on your device MORE - Switch between English and Japanese at any time in Settings - Light and dark themes, adjustable text size - Lecture materials from university courses (in Japanese) Whether you're writing your first lines of Python or brushing up on data science libraries, Python Study Notes keeps the essentials at your fingertips.

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)
