"The Zen of Python, by Tim Peters: Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Flat is better than nested. Sparse is better than dense. Readability counts. Special cases aren't special enough to break the rules. Although practicality beats purity. Errors should never pass silently. Unless explicitly silenced. In the face of ambiguity, refuse the temptation to guess. There should be one-- and preferably only one --obvious way to do it. Although that way may not be obvious at first unless you're Dutch. Now is better than never. Although never is often better than *right* now. If the implementation is hard to explain, it's a bad idea. If the implementation is easy to explain, it may be a good idea. Namespaces are one honking great idea -- let's do more of those!"

— from PEP 20 -- The Zen of Python, 1999

"The joy of coding Python should be in seeing short, concise, readable classes that express a lot of action in a small amount of clear code — not in reams of trivial code that bores the reader to death."

— from Blog post

"I'm a benevolent dictator for life, but I'm not a dictator. I'm a benevolent dictator for life, but I'm not a dictator. I'm a benevolent dictator for life, but I'm not a dictator."

The most important thing is to have fun while programming.

Various interviews/talks

Beautiful is better than ugly.

The Zen of Python (PEP 20) 1999

I am the benevolent dictator for life (BDFL).

Python community

I chose Python as a working title for the project, being in a slightly irreverent mood (and a big fan of Monty Python's Flying Circus).

The Python Tutorial

Don't you hate code that's not properly indented? Making it part of the syntax was one of my best decisions.

Various interviews

The joy of coding Python should be in seeing short, concise, readable classes that express a lot of action in a small amount of clear code — not in reams of trivial code that bores the reader to death.

Blog post

I've never programmed in Java, so I can't really say anything about it.

Interview

The GIL is one of the biggest stumbling blocks for people who want to use Python for high-concurrency applications.

Interview

I'm not a fan of design patterns as a silver bullet. Often they add unnecessary complexity.

Talk

I'd rather have a language that is easy to learn and easy to remember, even if it's not as powerful.

Interview

My original goal for Python was to make it a language that I enjoyed using.

Essay

Python's 'batteries included' philosophy means you can do real work without hunting for third-party libraries.

Python documentation

The problem with threads is that they are hard to get right.

Talk on concurrency

I'm not dead yet! (On retiring as BDFL).

Mail to python-committers 2018

I've given up the BDFL title, and I'm not planning to appoint a successor.

Mail to python-committers 2018

Python succeeded despite my many mistakes, not because of my few brilliant decisions.

Interview

The use of significant whitespace was a controversial decision, but I'd make it again.

Interview

I never expected Python to become as popular as it did.

Interview

Perl's 'there's more than one way to do it' is not the ideal I strive for.

Comparison with Perl

Python is a glue language. It's great for connecting components written in other languages.
