I wrote Python for weeks before I realised I only knew 2 of the 7 data types. Here’s the full picture: ① int → whole numbers (age, count, rank) ② float → decimals (price, score, coordinates) ③ str → any text in quotes ④ bool → True or False only — but used everywhere ⑤ list → ordered, changeable collection ⑥ tuple → ordered, locked. Cannot be changed. ⑦ dict → key-value pairs. The foundation of JSON and APIs. One thing nobody warns you about: int(3.9) = 3. Not 4. Python truncates — it does not round. This broke my code the first time. Now you know before it breaks yours. Day 7 of learning Python for data science — documenting everything so you don’t start from zero.
