Hello

I am trying to make a list of things which can be difficult/surprising to someone who is changing language from PHP to Python.

so far i have rather short list:

• forget require / include, learn import (this was most difficult to me - to understand package - module - class - object hierarchy and its mapping to filesystem)
• you can't just upload file on server to have webpage (->mod_python, wsgi etc)
• learn the python way for use variable class names (new $class() vs import + getattr)
• / operator in python 2.x and all float-related horrors

those were difficult to me, it takes few days before mind adapts a new paradigm

after i found that there is few other areas which could be challenging for someone with (too) many years of php:

• everything is an object
• you have to live with exceptions
• array vs list, set, dictionary, tuple ...
• learn (effective) list comprehensions
• learn generators

any other ideas / personal experiences ?
