next I notice that this did not match what was on page 42. There is no build folder.


>>> import nester
>>> cast = ['Palin', 'Cleese', 'Idle', 'Jones', 'Gilliam', 'Chapman']
>>> nester.print_lol(cast)
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
AttributeError: 'module' object has no attribute 'print_lol'

This is what I did in the shell.

def print_lol(movies):
for each in movies:
if isinstance(each,list):

This is my code.

What am I doing wrong? Is there something else I need to do. I tried this on several windows 7 computers and had the same results.
I was running 3.3 and thought it had something to do with that build. But I get the same results with 3.4

Sorry you are having trouble.

Please read this forum entry: http://forums.oreill...864#entry113864

I've just rechecked this again on Windows 7 using Python 3.4, and it worked fine. My code matches what's in the book, and is downloadable from the book's pages at the http://headfirstlabs.com site. Although things have changed a little since 2010 (when the book was written) the process still works.

I put the code in c:\nester, then built and installed the module, as per the instructions in the above-mentioned forum entry.

Here's a screenshot which shows you what to expect when the build/install commands are issued on Windows 7: http://python.itcarlow.ie/images/1.png

Here's a screenshot which shows the state of my nester folder after the build: http://python.itcarlow.ie/images/2.png

And here's a screenshot of the nester module being importing into Python 3 and used: http://python.itcarlow.ie/images/3.png

I hope these images and the above-mentioned forum entry help.

Hey David2.0,

I had the same problem, so I created the setup.py file again.
In my case, I misspelled "py_modules". I had used uppercase instead of lowercase
