Operators & Expressions
Learn how to use Python's arithmetic, comparison, logical, and assignment operators.
Learn how to use Python's arithmetic, comparison, logical, and assignment operators. This hands-on tutorial focuses on practical implementation of operators & expressions concepts.
Operators & Expressions
Operators are special symbols that perform operations on variables and values. Python divides operators into several groups.
Arithmetic Operators
Used to perform common mathematical operations.
Comparison Operators
Used to compare two values. They always return a Boolean (True or False).
Logical Operators
Used to combine conditional statements.
Assignment Operators
Used to assign values to variables.
Identity Operators
Identity operators (is, is not) are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location.
Membership Operators
Membership operators (in, not in) are used to test if a sequence is presented in an object.
Operator Precedence
Precedence determines the grouping of terms in an expression. It controls how an expression is evaluated. Acronym to remember: PEMDAS
- Parentheses
() - Exponentiation
** - Multiplication
*, Division/, Floor//, Modulus% - Addition
+, Subtraction-
