Tutorial

In Python, operators are special symbols, combinations of symbols, or keywords that designate some type of computation. You can combine objects and operators to build expressions that perform the actual computation. So, operators are the building blocks of expressions.

Learn all about how to perform definite iteration with Python "for" loops. You’ll see how other programming languages implement definite iteration, learn about iterables and iterators, and tie it all together to learn about Python’s for loop.

Course

Python list comprehensions make it easy to create lists while performing sophisticated filtering, mapping, and conditional logic on their members. In this course, you'll learn when to use a list comprehension in Python and how to create them effectively.

Course

Learn about the built-in Python Boolean data type, which is used to represent the truth value of an expression. You'll see how to use Booleans to compare values, check for identity and membership, and control the flow of your programs with conditionals.

Course

In this introductory Python course, you'll learn how to take user input from the keyboard with the built-in function input() and how to display output to the console with the built-in function print().

Course

Learn about the print() function in Python and discover some of its lesser-known features. Avoid common mistakes, take your "hello world" to the next level, and know when to use a better alternative.

Course

See two items to add to your Python string formatting toolkit. You'll learn about Python's string format method and the formatted string literal, or f-string. You'll learn about these formatting techniques in detail and add them to your Python string formatting toolkit.

Course

Learn how to define and call your own Python function. You'll also learn about passing data to your function and returning data from your function back to its calling environment.
