​Why Python?

First of all…..We need to understand Data Types!

Data Types

Many programming languages require you to state the type of data

you want to store in it.

The main data types are:

Integer

Real/Float

Boolean

Char

​Integer

Real

Boolean

String

Char

An integer is a whole number without a fractional part (decimal place).

Integer

Here are some examples of integers:

5 .75

People = 4

Score = 75

Age = 14

Real numbers (also known as floating point) can have a fractional

part (decimal place).

Real/float

© ZigZag Education, 2020

Here are some examples of real numbers:

5.75

Temperature =

18.5
Price = 1.84

Height = 1.85

The Boolean data type supports only two different values:

True and False.

Boolean

© ZigZag Education, 2020

These values are represented using binary.

0 = False

1 = True

Authorised =

True

Overdue =

False

The character data type stores a single alphanumeric character.

Character

© ZigZag Education, 2020

Here are some examples of characters:

This could be a letter, number or symbol.

Gender = F

Grade = B

Initial = H

A string is a group of characters.

String

© ZigZag Education, 2020

Here are some examples of strings:

Name = “Alex”
Postcode = “N1

5BH”

City =

“London”

Strings are usually enclosed within quote marks “ ”.

​name = input("What's your name? ") print("Hello, " + name + "!")

name = input("Enter your name: ")

age = input("Enter your age: ")

hobby = input("What's your favourite hobby? ")

#main code

print(f"Hi, I'm {name}, I'm {age} years old and I love {hobby}!")

​Turn & Talk

​Person A: I think this code...
Person B: I agree / want to build on that / want to challenge

Coding Task: Create an 'About Me' Program

Use your Python skills to write a short program that introduces you! This will help me learn more about you and see how confident you are with coding.

What to Include:

• input() – Ask for your name, age, and hobby

• print() – Display your answers in a creative way

• Variables – Store the information you collect

• String formatting – Use + or f-strings to combine text

​Challenge Yourself: Add more questions (favourite food, dream job, etc.) Use comments to explain your code.
Make it fun and personal!

Screenshot your code and add to your class notebook on Teams
