[Zope] [off topic] question?

Hi, Another question to all you Python programmers. To tell you the truth, I never heard about Python before I heard of Zope! I knew of Java. Do, it looks like Python is older then Java... How comes that Python is not so popular like Java (or not so known in Windows environment)? Like Java, Python is multi-platform. It can work on Windows as on Unix as on .... Are there any fundamental differences between Python and Java? I see Python has it's Java module (JPython) also... So, I don't get it... Why is Java so popular, while Python seems to be the same and is born before Java... Can somebody give me a easy explenation? Thanks, Tom.
