Python operators have a set order of precedence, which determines what operators are evaluated first in a potentially ambiguous expression. For instance, in the expression 3 * 2 + 7, first 3 is multiplied by 2, and then the result is added to 7, yielding 13. The expression is not evaluated the other way around, because * has a higher precedence than +. Learn More about Python Operator Precedence

Below is a list of operators by precedence, and a brief description of what they (usually) do.

## Simple Operator Precedence Examples in python

Python follows PEMDAS rule. PEMDAS stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction.

Example:

a, b, c, d = 2, 3, 5, 7

a ** (b + c) # parentheses

256

a * b ** c # exponent: same as`a * (b ** c)`

7776

a + b * c / d # multiplication / division: same as`a + (b * c / d)`

Extras: mathematical rules hold, but not always:

300 / 300 * 200

200.0

300 * 200 / 300

200.0

1e300 / 1e300 * 1e200

1e+200

1e300 * 1e200 / 1e300
