Chapter 1: A Python Primer

Operators

If you have programmed in other languages, the operators in Python will be familiar to you. The Python

operators are fundamentally similar to those used in other languages. In the code shown earlier, the

conditions evaluated in both

if statements involve comparison operators. The following table describes

the operators most commonly used in Python, and the ones used in this book:

Operator Symbol Example

Numeric Operators

Addition + x + y

Subtraction

−

x – y

Multiplication * x * y

Division / x / y

Exponent (Power) ** x ** y (x to the y power)

Modulo % x % y (the remainder of x/y)

Comparison Operators

Greater than > x > y (x is greater than y)

Less than < x < y (x is less than y)

Equal to == x == y (x equals y)

Greater than or equal to > = x > = y (x is greater than or equal to y)

Less than or equal to < = x < = y (x is less than or equal to y)

Not equal to != or < > x != y, x < > y (x does not equal y)

Boolean Operators

and and x and y (if both are true, then the expression is true)

or or x or y (if either is true, then the expression is true)

not not not x (if x is false, then the expression is true)

Assignment Operator

Assignment = X = 15

name = “ Jim ”
