Arithmetic operators are symbols used to perform mathematical operations in Python.
| Operator | Name | Example |
|---|---|---|
| + | Addition | x + y |
| - | Subtraction | x - y |
| * | Multiplication | x * y |
| / | Division | x / y |
| % | Modulus | x % y |
| ** | Exponentiation | x ** y |
| // | Floor division | x // y |
Note: The modulus operator (%) returns the remainder of a division between two numbers.
Note: Floor division (//) divides two numbers and returns the result rounded down to the nearest integer.
You can combine arithmetic operators to perform more complex calculations:
print(5 + 10 * 2)But be careful, always be clear when making more complex calculations.
Use parentheses to clarify your intent and control the order of operations:
print(6 / (2 * (1 + 2))) # Output: 1
print((6 / 2) * (1 + 2)) # Output: 9
