f2py problem

[Alberto Vera]

Hello.

After I installed f2py using Python, NumPy and Numarray software, I 
can't use f2py

I saw this error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'f2py' is not defined
 >>>

Could you tell me what is the problem?

Regards.
