portability

[Gillou]

Read carefully the docs of various APIs of the standard library and don'use
what's OS specific.
Some modules/packages are not available for Windows, others for Unix, and
others for classic MacOS.
Python is not as portable as Java, because standard Java API does not
provide system specific classes.
The main difference is :

* 100% pure java code is (supposed to be) portable.
* Python programmers must choose and use carefully the packages/classes to
provide portable applications. It's just like in C/C++.

In example, you can't get the value of an environment variable in "100% pure
Java".
You can't use COM objects in "100% pure Java".
You can't write Unix system utilities in "100% pure Java".
(...)
That's the price of Java portability.
