a named piece of data stored in a computer’s memory which can be accessed and changed by a computer program

a symbol or word that instructs the computer to perform a specific calculation or action

a sequence of characters, e.g. letters, numbers, spaces, and other symbols

a whole number that can be positive, negative, or zero

Working with numerical inputs

Computing

Writing a text-based program

Using selection

Selection with multiple paths

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

Which function in Python is used to get input from the user?

What data type does the `input()` function in Python always return?

Which Python function is used to convert a string representing a whole number into an integer?

asks the user for their age and stores it as an integer

asks the user for their age and stores it as a string

In Python, what does the following code do?
```print("Enter your age: ")
age = int(input())
```


An {{}} is a numerical data type which holds a whole number that can be positive, negative, or zero.

Arrange the following steps in the correct order to calculate the result of this Python expression:
```result = 2 + 4 * 6```
