NameError: name 'f2py' is not defined

after installing python, numpy and scipy_dist_utils i typed f2py onto the python interpretor the result is as below

>>> f2py
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    f2py
NameError: name 'f2py' is not defined
>>> import numpy
>>> f2py
Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    f2py
NameError: name 'f2py' is not defined

from numpy import f2py solved the problem but this does not work now f2py -c --help-fcompiler

f2py -c --help-fcompiler Traceback (most recent call last): File "", line 1, in f2py -c --help-fcompiler NameError: name 'c' is not defined

What has gone wrong? could anyone help me with this?

Robert Kern is correct. You cannot run it from within python. I had a similar error on my windows computer. The problem is that f2py is not in the path.

You'll have to call f2py in the following method from the command prompt.

python C:\Path\to\f2py.py

That should allow it to be called.

As an example, I have python 3.4 installed in the C directory in the folder Python34 with f2py in the subfolder Scripts. So, my call to f2py is python C:\Python34\Scripts\f2py.py.

If you are trying to run f2py, you do that from your command shell (bash or whatever on UNIX machines, CMD on Windows), not from the Python interpreter. There isn't a whole lot you can do with

Also, scipy_distutils is very, very old and not at all used anymore. Whatever instructions that told you to install that are incredibly out of date. For a somewhat more up to date set of instructions:
