L2 Python - Arithmetic

Question 1

Data Types:

Answer 1

• String holds alphanumeric data as text
• Integer holds whole number
• Float holds numbers with a decimal point
• Boolean holds either ‘True’ or ‘False’

Question 2

Maths Symbols in Python

Answer 2

• Multiply = *
• Power = **
• Divide = /
• Add = +
• Subtract = -
• Square root = math.sqrt

Question 3

Casting:

Answer 3

• Python automatically assigns a data type to a variable

- You can override this using Casting

Question 4

Concatenation:

Answer 4

Animal

• Concatenating means “to join together”
• The plus symbol (+) joins two strings together
• Don’t forget to add extra spaces to make your output look nice
• Using the comma (,) displays the variable with spaces around it

Animal = input(“Enter the name of an animal:”)

Description = input(“How would you describe a “ + animal + “ ? “)

Print (“A” ,animal, “is” ,description)

Print (“You will find it under “ ,animal, “ inthe dictionary”)

Question 5

Program to add two numbers together:

Answer 5

num1=int(input(“Enter first number to add”))
num2=int(input(“Enter second number to add”))
sum = num1+num2
multiply = num1*num2
print (“The total is “ + str(sum))

Question 6

Program to find hypotenuse of a triangle:

Answer 6

import math
num1=float(input("Enter the first short side "))
num2=float(input("Enter the second short side”))
num3=num1**2
num4=num2**2
num5=num3+num4
num6=math.sqrt(num5)
print ("Answer =" , num6)

Question 7

Program to find shorter side of a triangle:

Answer 7

import math
num1=float(input("Enter Hypotenuse "))
num2=float(input("Enter known short side "))
num3=num1**2
num4=num2**2
num5=num3-num4
num6=math.sqrt(num5)
print ("Answer =" , num6)
