## Data Types

## Python Simple Data Types

Python stores different types of information in different data types.

### Strings

These are used to store mixed text, passwords, sentences.

Examples:

- dog
- passw54£$%^123
- The cat sat on the mat

**Integers**

These are used to store **whole** numbers.

example:

- 435
- -323442

### Floats

These are used to store numbers with a decimal place values.

- 4.13234
- 0.00000000023

## Boolean

These are used to store True or False values

Examples:

- True
- False

## Basic Example

code:

size = input("What shoe size are you?") size = int(size) # Convert to a whole number #If you want to use decimal numbers like 4.5 then use size=float(size) instead if size > 10: print("You have big feet.") elif size < 3: print("You have tiny feet") else: print("You have normal sized feet")

## Challenge 9

**Challenge 9 – How’s the temperature?**

YouTube blocked at school? Try the Google Drive version

** Bronze**

- Ask the user the temperature and convert the temperature to an integer.
- If the temperature is above 30 degrees, tell the user it is hot today

**Silver**

- If the temperature is below 5 degrees, tell the user the it is cold.
- Use the os.system(‘clear’) function to add system clears to your program.

** Gold**

- If the user enters any amount outside of the valid range ( – 50c ./ + 50c) , they should be told that they have entered an invalid value.

## 10

**Challenge 10 – Calculate the area of a rectangle.**

** Bronze**

- Ask the user to enter the length and width of a rectangle.
- Convert the inputs to integers.
- Output the area of the rectangle.

**Silver**

- Use the .strip() method to remove spaces before and after the user’s input.
- Also calculate the perimeter of the rectangle and output the perimeter as well.

** Gold**

- Ask the user to enter the lengths and widths of 2 rectangles.
- Calculate the area of both and output which rectangle is higher.

## 11

**Challenge 11 – Calculate the missing triangle angle**

The angles of a triangle always add up to 180 degrees.

** Bronze**

- Ask the user to enter 2 angles of a triangle and convert the values to
**integers** - Work out the third angle and output it to the user.

**Silver**

Check each of the values entered to ensure that they are valid ( less than 180 degrees in total) and print out an appropriate response if they don’t enter a valid amount.

** Gold**

- Check the values entered and calculated to work out of the triangle if the triangle is either:
- Equilateral – All angles equal size.
- Isosceles – Two angles equal size.
- Scalene – All angles of different size.

- Print out an appropriate amount.

## 12

**Challenge 12 – Reaction Timer Game**

Create a program that tests the user’s reaction time.

*** To complete this challenge you need to watch the advanced tutorial ***

** Bronze**

- Get the program to wait a random amount of seconds and then ask the user to press enter.

**Silver**

- Record the time the message was displayed and the time the user pressed enter. Work out the response time and print it out to the user.
- use the round() function to convert the user’s float to 2 decimal places.

** Gold**

- If the user took less the 0.1 seconds, tell them well done.
- If the user took longer than 0.5 seconds, tell them their reaction time is too slow.
