learnpython.org is a free interactive Python tutorial - one of the Interactive Tutorials websites. Interactive Tutorials is a personal project of mine aimed at making everyone in the world be able to learn how to code for free.

Functions are a convenient way to divide your code into useful blocks, allowing us to order our code, make it more readable, reuse it and save some time. Also functions are a key way to define interfaces so programmers can share their code. How do you write functions in Python? As we have seen on previous tutorials, Python makes use of blocks.

Python is completely object oriented, and not "statically typed". You do not need to declare variables before using them, or declare their type. Every variable in Python is an object. This tutorial will go over a few basic types of variables. Numbers Python supports two types of numbers - integers (whole numbers) and floating point numbers ...

This section explains how to use basic operators in Python. Arithmetic Operators Just as any other programming languages, the addition, subtraction, multiplication, and division operators can be used with numbers.

Essentially, these three functions allow you to apply a function across a number of iterables, in one fell swoop. map and filter come built-in with Python (in the __builtins__ module) and require no importing. reduce, however, needs to be imported as it resides in the functools module.

When programming, errors happen. It's just a fact of life. Perhaps the user gave bad input. Maybe a network resource was unavailable. Maybe the program ran out of memory. Or the programmer may have even made a mistake! Python's solution to errors are exceptions. You might have seen an exception before.
