Error in importing a python file

Question

I've written a python file and am trying to import it but it's not recognized. The file was saved as gentleboost_c_class.c in C:\User\apps\My documents. I tried to import it like this:

import gentleboost_c_class as gbc

But I get this error:

NameError: name 'gentleboost_c_class' is not defined

gentleboost_c_class.py begins like this:

from sklearn.externals.six.moves import zip
import numpy as np
import statsmodels.api as sm
class GentleBoostC:

.....

It compiles fine. Both files are in the same folder. What am I doing wrong?

How is python going to know where gentleboost_c_class is located? — Elias Benevedes

Where is the file that you're importing from located? (i.e. not gentleboost_c_class.py but the other file) — s16h

You're getting a NameError, not an ImportError. Seems to me that you import your module as gbc, but later try to refer to it as gentleboost_c_class. — Lukas Graf

Both files the one I'm importing into, and the one I'm importing, are in the same folder, as I just mentioned at the end of the question. — user961627

@user961627 that's a different problem then. As the error message states, a module object is not callable, but you're trying to do that with gbc(). What are you actually trying to do? Instanciate the class GentleBoostC? Then it would be gbc.GentleBoostC(). — Lukas Graf

You're getting a NameError, not an ImportError.

So it seems to me that you import your module as gbc, but later try to refer to it as gentleboost_c_class.

If you import the module with

import gentleboost_c_class as gbc

that means it will be available under the global name gbc, but not as gentleboost_c_class.
