Summary

Operators in Python include arithmetic for computation, comparisons to compare values, logic to combine conditions, to assignments such as += that update the value of a variable. Each operator has a rule of priority that determines the order of the calculations, and parentheses can be used to force a particular order. Understanding operators well makes our expressions accurate and easy to read.
