Lesson 3: Operators & Expressions

1. Arithmetic Operators

+ addition
- subtraction
* multiplication
/ division (always float result)
// floor division (integer result)
% modulus (remainder)
** exponentiation

Examples:

5 + 3 = 8
10 / 4 = 2.5
10 // 4 = 2
10 % 4 = 2
2 ** 3 = 8

Exercise 1

Compute:


17 // 5 = 
17 % 5 = 
3 ** 4 =

2. Comparison & Logical Operators

Comparison:

== equal
!= not equal
> greater than
< less than
>= greater or equal
<= less or equal

Logical:

and (both true)
or (at least one true)
not (invert)
