I've tried to run lengthcounter_lutz from the file's folder and this worked
out.
cd /Users/Username/Python_modules/
python /Users/Username/Python_modules/lengthcounter_lutz.py

But I can't understand what's wrong with the second one:

file = open(name.__file__)
return len(file.readlines())

import lengthcounter
print test(lengthcounter)
import lengthcounter
lengthcounter.test(lengthcounter)
('Lines:', 5, 'Chars:', 885)
Looking at page 1119 in the learning Python book, I might venture a
guess as to where the difference lies. You are calling test as:
test(lengthcounter), but that is not the name of a file (the name of a
file should be in quotes). lengthcounter in this case is a variable,
not a filename. The behavior in this case is probably undetermined.
I suggest doing a manual check on the file named lengthcounter.pyc, and
I'll bet you will find something closer to 5 lines and 885 characters.
pyc files are the bytecode version of your file that gets generated
automatically and is the code that is actually executed.
Somehow, calling the method test inside the interpreter is different
from running it on the commandline and you are picking up the pyc file.
In either case, this format is iffy at best:
if __name__ == '__main__':
import lengthcounter
print test(lengthcounter)
should really be:
if __name__ == '__main__':
import lengthcounter
print lengthcounter.test(lengthcounter)
to avoid ambiguous behavior.

Neither do I but you can debug it easily from the prompt by calling
the individual lines/functions. Try:
import lengthcounter as lc
print lc.__file__ # to check it's using the expected file
# assuming it is...
print (open(lc.__name__),read()) # check the contents is what we
expect
print ( len(open(lc.__name__),read()) ) # check the length result
print ( len(open(lc.__name__),readlines()) ) # check the lines

Python uses PYTHONPATH to find modules when you import them.
So when we do import lengthcounter above we dont need to be in the same
folder as lengthcounter.py to be able to import it.

Re: [Tutor] PYTHONPATH (Mac OS X)
Simply that python is saying it cannot find the file.
So it is probably in a different folder to the one in which the program is
running. You need to provide a valid path to the file,
Those files are in the same folder:
/Users/Username/Python_modules/
I don't want to write a full path here:
if __name__ == '__main__':
print test('lengthcounter_lutz.py')
How to add this directory to the search path?
So what is it doing exactly that seems wrong?
What input? What output? What did you expect?
I have a slightly different copy of this file:
def countLines(name):
file = open(name.__file__)
return len(file.readlines())
def countChars(name):
return len(open(name.__file__).read())
def test(name):
return Lines:, countLines(name), Chars:, countChars(name)
if __name__ == '__main__':
import lengthcounter
print test(lengthcounter)
I've tried to run it in the interactive shell:
import lengthcounter as lc
lc.test(lengthcounter)
And here is the output:
('Lines:', 5, 'Chars:', 885)
But that code has 13 lines and 317 characters according to the Emacs' counter.
Where is an error?
Cheers.

Once again, there is no search path for the open() function. You can
either supply an absolute name (eg. starting with leading slash), or you
can supply a path relative to the current directory. If you're not sure
what the current directory is, you can fetch it with something like:
import os
print os.path.abspath(os.curdir)
But if you're running the script from the terminal window, it should
simply be the current directory for that window. If you're running it
from some other shell, you'd have to consult that shell's docs.

Those files are in the same folder:
/Users/Username/Python_modules/
And is that where you are running the code from? That is the critical
factor.
By just providing the filename Python assumes its in the same folder
that you ran the program from. If you run it from somewhere else you
*must* provide the full (or relative() path to the file. There is no
option for Python to search for it.
I don't want to write a full path here:
if __name__ == '__main__':
print test('lengthcounter_lutz.py')
You don't have any option.
You either type in the full path or you get the user to tell you

print test(lengthcounter)
I've tried to run it in the interactive shell:
import lengthcounter as lc
lc.test(lengthcounter)
Are you sure it is your version that's being picked up?
Try renaming it to something guaranteed to be unique. See if the results
are the same.
Also I would expect the prompt to complain because you are passing
lengthcounter as a name to the test function, but you imported
lengthcounter as lc, so python should not know about lengthcounter
unless you had already imported it (or another file?)
eg.
import random as r
random.__file__
Traceback (most recent call last):
File stdin, line 1, in module
NameError: name 'random' is not defined
Try starting a fresh interpreter session and repeating the test.

Re: [Tutor] PYTHONPATH (Mac OS X)
Hey there!
I'm reading Lutz's Learning Python.
Here is some code from the book.
There is a module called lcclient_lutz.py:
from lengthcounter_lutz import countLines, countChars
print countLines('lengthcounter_lutz.py'), countChars('lengthcounter_lutz.py')
And there is another one called lengthcounter_lutz.py:
def countLines(name):
file = open(name)
return len(file.readlines())
def countChars(name):
return len(open(name).read())
def test(name):
return Lines:, countLines(name), Chars:, countChars(name)
if __name__ == '__main__':
print test('lengthcounter_lutz.py')
I've got an error while trying to load lcclient_lutz module:
python /Users/Username/Python_modules/lcclient_lutz.py
Traceback (most recent call last):
File /Users/Username/Python_modules/lcclient_lutz.py, line 2, in module
print countLines('lengthcounter_lutz.py'),
countChars('lengthcounter_lutz.py')
File /Users/Username/Python_modules/lengthcounter_lutz.py, line 2,
in countLines
file = open(name)
IOError: [Errno 2] No such file or directory: 'lengthcounter_lutz.py'
How to fix it? Is it connected with the PYTHONPATH variable?
P.S. There might be an error in the lengthcounter_lutz module, because
it makes mistakes while counting.
Kind regards.

PYTHONPATH only helps Python find the files to import.
Since the error message is pointing at code insiude the imported
functions then clearly PYTHONPATH is working just fine.
So what is the error?
Simply that python is saying it cannot find the file.
So it is probably in a different folder to the one in which the program
is running. You need to provide a valid path to the file,
P.S. There might be an error in the lengthcounter_lutz module, because

Thats possible. Or it may e worlking to a different definition of
success to the one you expect! Counting words and letters is quite a
subjective past-time.
So what is it doing exactly that seems wrong?
What input? What output? What did you expect?

First rule: include the complete error message, including the traceback. Also, make sure you copy/paste the message, not paraphrase or retype it.

Sincerely, Chris I'm not sure it's still the preferred way of setting sys.path, but site.py sets sys.path and contains info on *.pth files and other methods used.

You set the variable in your system's environment, which is platform-dependent. For Linux, you'd typically put a line in your ~/.profile or ~/.cshrc or ~/.login or ~/.bashrc or whatever your shell uses per your account set up. So, for example, in a bash/sh shell, you'd say: export PYTHONPATH=/path/to/my/modules or for csh: setenv PYTHONPATH /path/to/my/modules Then starting the next time you log in, that will be set in your environment for you.
