Selection with multiple paths

Computing

Writing a text-based program

Working with numerical inputs

Using selection

Iteration using while loops

Building a program using control structures

This unit introduces pupils to text-based programming with Python. Pupils start with programs involving input and output, and gradually move on to using arithmetic operations, randomness, selection, and iteration. Pupils will consolidate these skills in a project at the end of the unit.

Introduction to Python programming

You can have more than two options for your code to choose from.

The computer checks each condition in order.

All the code inside every `if`, `elif`, and `else` block runs.

It helps your program make different choices based on what's True.

Which of the following statements accurately describes multi-path selection in Python?

In Python, what is used to introduce an additional condition in a multi-path selection statement after an initial if statement?

What will be the output of the following Python code?

```grade = 75

if grade >= 90:
    print("A")
elif grade >= 80:
    print("B")
elif grade >= 70:
    print("C")
else:
    print("Fail")```

 to make the code look visually appealing.

to indicate which lines of code belong to which block or path of the selection.

to specify the order in which the conditions should be evaluated.

to define the data types of variables used in the conditions.

What is the primary purpose of indentation in Python code, especially in the context of `if`, `elif`, and `else` statements?

The first condition needs to be True before the next condition can be run.

The first condition needs to be False before the next condition can be run.

Which of the following is correct when describing nested if statements?

A game gives points based on a dice roll:

Roll 1 or 2: lose a point.
Roll 3, 4, or 5: no change.
Roll 6: win a point.

Which Python code is best for this?

Which of the following Python expressions evaluates to `True`?

Which Python code is used to create a block of code that will run based on whether something is True or False?

What is the output when the program is run?

```score = 7
if score > 5:
    print("score is greater than 5")
else:
    print("score is not greater than 5")```

Which logical operator in Python checks if two conditions are **both** True?

What will be the output of this Python code?
```is_raining = True
is_cold = False

if is_raining or is_cold:
    print("Stay indoors")
else:
    print("You can go outside!")```

code to execute if the condition is False

Arrange the following components of an if-else statement in the correct order.
