[Tutor] Application packaging

[Carlos Daniel Ruvalcaba Valenzuela]

Hello list,

Lately I have been working on a windows desktop application for a client,
using python and pyside, everything working fine, but I'm getting a bit
stuck when trying to distribute the application to the client.

Currently I'm using a combination of py2exe and clickonce, what are your
experiences on distributing this kind of applications on a windows
environment?

Personally I have tried py2exe, pyinstaller, cx_freeze, only py2exe got me a
working bundle but a ugly one full of unordered files, I wrapped all this on
a ClickOnce installer so the user just sees an icon in their desktop. The
problem with this approach is that it results in a huge bundle, updates are
a pain too. Any ideas or experience with this (not precisely this combo but
the packaging in general)?

Regards,
Carlos Ruvalcaba

PD: I'm looking for the actual state of things right now as I'm sure this
questing has been asked in the past.

filepath is a unicode string, your library seems to expect byte strings.
Try converting it like so:

import sys
filesystemencoding = sys.getfilesystemencoding()
#...
shapeData = ogr.Open(filepath.encode(filesystemencoding))

Hello guys!!!
Shame on me, you're rigth I missunderstood the function and the module.
I change the name of my function and that part of my code worked.
But now I get a differente error, this script is going to collect
information from shapefiles, I asked the user where to start the search, the
file extension, and the csv name. Now I get:
>>> import win
>>> Seleccione directorio donde empezar
You chose C:/
Escribe la extension que necesitas buscar
Buscando archivos:  .shp
Nombre del csv a crear
Archivo de salidad:  gui.csv
Iniciando...
Exception in Tkinter callback

Yes, the csv module has a writer function.  But read carefully!  The error
message isn't saying that the csv module doesn't have a writer function --
it says **function object** has no attribute 'writer'.  So... somehow Python
thinks that the name 'csv' refers to a function at the point in the code
where the error is thrown.  So how can this be?  You should be asking
yourself this question -- could it be that you've (for example) defined a
*function* called 'csv', thereby effectively effectively hiding the *module*
csv?  ;)

You have a function called "csv()" in your code.

So when you go csv.blahbittyblob, you've overriden your imported module
called "csv" with the function called "csv", python then tries to look up
the attribute blahbittyblob and can't find it. it then throws an error.

Change your csv function to be csvx() or _csv or something other than csv

I want to write a csv file, but I need the final user to give me some values
to open and update the file. My code is:
