Math Says Yes vs Python, Step by Step

Most statistics sound wrong at first. In a room of 23 people, the odds of a shared birthday are already even. On a game show with three doors, switching after the host opens one doubles your chance of winning. A poll of 1,000 strangers can read a whole country. Math Says Yes is a feed of facts like these, each one explained until the surprise turns into something obvious. Open the app and start scrolling. Every fact is short and sourced, built around a single idea from probability or data. Most come with a quick question that catches your gut before it shows the answer, plus a small chart or a slider you can play with to watch the number move. What's inside: - A scrolling feed of counterintuitive statistics, from the birthday paradox to why tiny samples lie - Quick-check questions tuned to the exact intuition people get wrong - A daily challenge of five questions, so you can find out whether you beat your own guessing - Search and topics for digging into probability, sampling, averages, or plain randomness - Saved facts and a "learned" marker to track what has actually stuck - A glossary that explains the jargon in one paragraph instead of one textbook It costs nothing to read and needs no signup to start. Sign in only if you want to sync saved facts and progress across devices or build a streak. Made for the people who liked statistics in theory but never quite trusted it, and for anyone who enjoys being pleasantly wrong about numbers.

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)
