Maths in Python

[ slide 5 ]

1. Copy the table

2. Race a friend with a calculator to see whether Python is faster than a calculator:

a) 5 * 6.5 =

b) 7 / 3 =

c) 128 + 6 =

d) How many times does 120 divide by 7?

e) What is the remainder of 120 / 7?

Combining Maths and Text

[ slide 7 ]

The print() function will print to screen:

strings, numbers or calculations separated by commas:

Interactive session:>>> print("111 divided by 4 = ", 111/4)

111 divided by 4 = 27.75

>>> print("11 divided by 4 = ", 11/4)

11 divided by 4 = 2.75

What will the output from this code produce?

>>> print("11 divided by 4 = ", 11//4, "remainder ", 11%4)

11 divided by 4 = 2 remainder 3>>> print("I will not write code in history lessons.\n" *50)

See what else you can produce.

Can you fill the screen with your name?

Now try entering this code:
