Introduction & Learning Objectives

Learning Objectives Identify and define three types of control structures: sequential, conditional, and loops. Write a Python `if-elif-else` statement to make a robot make a decision based on sensor data. Use a `for` loop with a variable to make a robot repeat an action a specific number of times. Use a `while` loop to make a robot repeat an action until a condition is met. Explain the importance of indentation in Python control structures. Debug simple Python code involving incorrect conditional logic or loop structure. How does a robot vacuum know to turn away from the stairs or a delivery drone know when to drop a package? 🤔 We're going to learn the secret code that gives robots their smarts! In this lesson, you will learn about 'Control Structures', whic...

Key Concepts & Vocabulary

TermDefinitionExample Control StructureA block of code that decides the order in which other code instructions are executed. It controls the 'flow' of the program.An `if` statement is a control structure that tells the robot: IF you see a wall, THEN turn left. Conditional Statement (if/elif/else)A control structure that performs different actions depending on whether a condition is true or false. It helps a robot make choices.`if battery_level < 20: robot.find_charger()` LoopA control structure that repeats a block of code over and over again. There are two main types: `for` loops (repeat a set number of times) and `while` loops (repeat as long as a condition is true).`for i in range(4): robot.move_forward()` makes the robot move forward 4 times. VariableA container for stori...

Core Syntax & Patterns

The `if-elif-else` Structure if condition1: # code to run if condition1 is True elif condition2: # code to run if condition1 is False and condition2 is True else: # code to run if all above conditions are False Use this to make your robot choose between two or more options. The `if` is always first. You can have as many `elif` (else if) blocks as you need. The `else` is optional and runs if nothing else was true. The `for` Loop with `range()` for variable in range(number): # code to repeat Use this when you know exactly how many times you want the robot to repeat an action. The `variable` (often `i`) will count from 0 up to, but not including, the `number`. The `while` Loop while condition: # code to repeat Use this when you want the robot to repe...
