You've learned the building blocks of every Python program. Variables store data. Data types (int, float, str, bool) categorize that data. Operators let you manipulate values.
You can now create variables with meaningful names, convert between types, do arithmetic, work with strings using concatenation, slicing, and f-strings, and solve basic HackerRank problems. You solved three problems: arithmetic operators, division, and loops.
Each reinforced the input-process-output pattern that underlies most programming. In the next section, you'll learn to make decisions. Instead of running every line in order, your programs will choose different paths based on conditions. That's where things get interesting.
