I'm planning on moving to Python and I have a couple of additional questions along with the title:

did you have more fun with python?
are you as productive as when you're using PHP?
what made you change to python?
Would you do a project again in PHP? If so, why?

Your answers would really be useful for us PHP devs wanting something more I guess :)
Thanks in advance!
I'll try my best to answer your questions as best I can:

Did you have more fun with python?

I really enjoy how minimalist python is, having modules with non-redundant naming conventions is really nice.  I found this to be especially convenient when reading/debugging other peoples code.  
I also love all of the python tricks to do some very elegant things in a single line of code such as list comprehensions and the itertools library.  
I tend to develop my applications using mod_wsgi and it took some time to wrap my head around writing thread-safe web applications, but it was really worth it.  
I also find unicode to be much less frustrating with python especially with python 3k.

are you as productive as when you're using PHP?

For simple websites python can be less fun to setup and use.  One nice feature of PHP that I miss with python is mixing PHP and HTML in the same file.  Python has a lot of nice template languages that make this easy as well, but they have to be installed.  

what made you change to python?

I became frustrated with a lot of the little nuances of PHP such as strange integer and string conversions and so forth.  I also started to feel that PHP was getting very bloated with a lot of methods with inconsistent naming schemes.  I was referring to the PHP documentation quite frequently despite having a large portion of the php library memorized.

Would you do a project again in PHP? If so, why?

I would develop a PHP project again, it has a lot of nice features and a great community.  Plus I have a lot of experience with PHP.  I'd prefer to use python, but if the client wants PHP I'm not going to force something they don't want.
PHP devs that moved to Python, is the experience better?
