Who I Am

I am the author of the Python programming language. See also my resume and my publications list, a brief bio, assorted writings, presentations and interviews (all about Python), some pictures of me, my new blog, and my old blog on

This web page is not one of my priorities. Much of the information here is several years old, and although still correct, not necessarily very relevant. I do try to make sure that all the links work, from time to time.

In December 2005 I joined Google in Mountain View, CA. I knew Google's services to be awesome; to work there is even better. But best is that I get to spend half my time on Python, no strings attached!

In July 2003, I left Zope Corporation to go work for Dan Farmer's new company, Elemental Security in San Mateo, California. I have moved with my family to the San Francisco bay area. For better or for worse, the news made Slashdot...

In June 2003, I was finalist in the category "IT - Software (Individual)" of the World Technology Network awards.

In May 2003, I received the NLUUG Award 2003 for extraordinary services to the community of users of Unix and Open Systems.

In February 2002, I was given the Free Software Foundation Award.

On November 5, 2001, my son Orlijn was born.

From October 2000 through July 2003, I work for Zope Corporation, makers of Zope. Read about the transition.

From May through October 2000, I worked for Unfortunately, this stint was not a success for me or for the PythonLabs team (who moved with me to Zope Corporation). Before that, I worked from 1995 through 2000 for CNRI in Reston, Virginia, and before that from 1982 through 1995 for CWI in Amsterdam.

In May 1999, I received the Dr. Dobb's Journal 1999 Excellence in Programming Award, together with Donald Becker.

How to Reach Me

You can send email for me to guido (at) I read everything sent there, but if you ask me a question about using Python, it's likely that I won't have time to answer it, and will instead refer you to help (at) or comp.lang.python. If you need to talk to me on the phone or send me something by snail mail, send me an email and I'll gladly mail you instructions on how to reach me.

My Name

My name often poses difficulties for Americans.

Pronunciation: in Dutch, the "G" in Guido is a hard G, pronounced roughly like the "ch" in Scottish "loch". (Listen to the sound clip below.) However, if you're American, you may also pronounce it as the Italian "Guido". I'm not too worried about the associations with mob assassins that some people have :-)

Spelling: my last name is two words, and I'd like keep it that way, the spelling on some of my credit cards notwithstanding. Dutch spelling rules dictate that when used in combination with my first name, "van" is not capitalized: "Guido van Rossum". But when my last name is used alone to refer to me, it is capitalized, for example: "As usual, Van Rossum was right."

Alphabetization: in America, I show up in the alphabet under "V". But in Europe, I show up under "R". And some of my friends put me under "G" in their address book...
