Python operators enable you to perform computations by combining objects and operators into expressions. Understanding Python operators is essential for manipulating data effectively.

This video course covers arithmetic, comparison, Boolean, identity, membership, bitwise, concatenation, and repetition operators, along with augmented assignment operators. You’ll also learn how to build expressions using these operators and explore operator precedence to understand the order of operations in complex expressions.

By the end of this video course, you’ll understand that:

  • Arithmetic operators perform mathematical calculations on numeric values.
  • Comparison operators evaluate relationships between values, returning Boolean results.
  • Boolean operators create compound logical expressions.
  • Identity operators determine if two operands refer to the same object.
  • Membership operators check for the presence of a value in a container.
  • Bitwise operators manipulate data at the binary level.
  • Concatenation and repetition operators manipulate sequence data types.
  • Augmented assignment operators simplify expressions involving the same variable.

00:00 Hello, welcome to Python Operators and Expressions. I’m Joseph, and I’ll be your explainer guy for this video course. When you start learning any programming language, one of the first things you’ll want to get a handle on is the syntax, which is kind of like the grammar of the language, the rules around how to write it, essentially. In Python, a huge part of this is understanding its various operators and using them to build expressions.

00:23 They give you easy access to a bunch of useful computations, but because they have their own sets of rules, they can seem a little mystifying at first. However, once you understand their subtleties and nuances, you’ll find yourself with some powerful new tools in your toolkit.

00:37 So whether you’re still new to these concepts or you just want to solidify your knowledge, this is the course for you.

00:44 By the end of this course, you’ll be able to understand and apply Python’s built-in operators, distinguish between unary, binary, and ternary operators.

00:53 Recognize how expressions differ from statements, perform mathematical calculations with arithmetic operators, work with operators that return Boolean results, and build logical expressions with Boolean operators.

01:09 While this is a course meant to be understood by Python users of all levels, it’ll help if you’re comfortable with Python basics like variables, assignments, and built-in data types. For a refresher on data types, I suggest Basic Data Types in Python: A Quick Exploration.

01:26 And if you’re ready to get started, meet me in the next lesson where we’ll begin with an overview of operators and expressions.
