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.
a, b, c, d = 2, 3, 5, 7
a ** (b + c) # parentheses
a * b ** c # exponent: same as
a * (b ** c)
a + b * c / d # multiplication / division: same as
a + (b * c / d)4.142857142857142
Extras: mathematical rules hold, but not always:
300 / 300 * 200
300 * 200 / 300
1e300 / 1e300 * 1e200
1e300 * 1e200 / 1e300
