Control Flow: Conditionals and Loops

Control Flow: Conditionals and Loops

Control flow determines the order in which your program's statements run.

What you will learn

• if statements to branch on conditions
• Loops to repeat work over collections and ranges
• Combining conditionals and loops to express real logic

Why it matters

Data work is repetitive by nature — you rarely process one row, you process thousands. Loops and conditionals are how you express that.
