Well, I think I must answer to my own post... There is at least one reason to bother with executables. I have just read a message. Someone wanted to run a program written in Python + wxPython. But he has failed. Why? Because the version of wxPython on his system was newer and it's API was different.
Of course he could install an older (the proper) version of wxPython as well... But he's not a developer. He don't know how to install Python, wxPython and so on... And he's not interested in such knowledge. So there *is* a reason for making executables. -- http://mail.python.org/mailman/listinfo/python-list
