I've been hacking a bunch of Python code recently: SCons, Buildbot, Twisted, SWIG bindings, etc. It has been a long time since I touched a line of Python (I worked with Zope and did some wxPython), but I still remember how to code Python.
There are still some issues I cannot understand:
why len(list) instead of list.length?
why are not regular expressions built into the language?
def foo(self, bar), str(4), etc. and so on
Nevertheless, I prefer writing Python rather than Java, my wrists don't hurt so much :)
