Question

I am working on a python program that will prompt the user to select files (.txt) and then write these file names to a text file. I am thinking I am on the right track but this is not working for me and I do not know why. It creates the file list .txt but does not place the filenames into the text document.

import Tkinter, tkFileDialog
root = Tkinter.Tk()
files = tkFileDialog.askopenfilenames(parent = root, title = "Select files...", multiple =1)
SPSSList = open('list.txt', 'w')
SPSSList.write(files)
SPSSList.close()

Sorry if I am missing something obvious and I appreciate any help.

Answer 1

file.write takes a string; askopenfilenames returns a tuple of filenames.

Use

for f in files:
    print >> SPSSList, f

if you want to write them each on a separate line. Alternately,

SPSSList.write('\n'.join(files))

is somewhat more flexible since you can choose to use a different separator (e.g. ','.join).
