Do you use Python mostly for its functional or object-oriented features?

I see what seems like a majority of Python developers on StackOverflow endorsing the use of concise functional tools like lambdas, maps, filters, etc., while others say their code is clearer and more maintainable by not using them. What is your preference?

Also, if you are a die-hard functional programmer or hardcore into OO, what other specific programming practices do you use that you think are best for your style?

Thanks in advance for your opinions!
