Basic Operators - Learn Python - Free Interactive Python Tutorial 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. number = 1 + 2 * 3 / 4.0 Execute Code Try to predict what the answer will be. Another operator available is the modulo (%) operator, which returns the integer remainder of the division. dividend % divisor = remainder. remainder = 11 % 3 Using two multiplication symbols makes a power relationship. squared = 7 ** 2 cubed = 2 ** 3 Using Operators with Strings Python supports concatenating strings using the addition operator: helloworld = "hello" + " " + "world" Python also supports multiplying strings to form a string with a repeating sequence: lotsofhellos = "hello" * 10 Using Operators with Lists Lists can be joined with the addition operators: even_numbers = [2,4,6,8] odd_numbers = [1,3,5,7] all_numbers = odd_numbers + even_numbers print [1,2,3] * 3

InMusic This page is divided in three sections: Music software written in Python, Music programming in Python, and Music software supporting Python Bluemindo - Bluemindo is a really simple but powerful audio player in Python/PyGTK, using Gstreamer. Bluemindo is a free (as in freedom) software, released under GPLv3, only. cplay - a curses front-end for various audio players edna - an MP3 server, edna allows you to access your MP3 collection from any networked computer. The web pages are dynamically constructed, adjusting to directory structure and the files in those directories. This is much nicer than using simple directory indexing. Dive Into Python 3 Python Introduction Tutorial First, off Python usually requires some setup by downloading the Python IDLE. The Python IDLE is basically a text editor that lets you execute Python code. If you want to use Python as a server-side language, you certainly can. Python can output HTML just like other languages can, but Python is more commonly used as a module rather than intertwined like some PHP or ColdFusion. As for right now, I recommend you download the IDLE to help you debug your code while we learn the fundamentals offline. You can see right off the bat, that we use print() a whole lot. See how simple that was? For a more tangible and better look into the Python language, consider reading the following book. Your code will execute in this window.
