The standard Python distribution does not come, as of this writing, with the numarray Python extensions installed, but your system administrator may have installed them already. To find out if your Python interpreter has numarray installed, type "import numarray" at the Python prompt. You'll see one of two behaviors (throughout this document user input and python interpreter output will be emphasized as shown in the block below):
>>> import numarray Traceback (innermost last): File "<stdin>", line 1, in ? ImportError: No module named numarray
>>> import numarray >>> numarray.__version__ '0.6'
