I’m trying to get a list of filenames from tkinter.filedialog.askopenfilenames() in Python 3.2.
files = askopenfilenames(initialdir="C:\Users\BVCAP\Videos", title="Select files")
self.num_files.set(len(files))
I was expecting the output to be a tuple (or maybe a list) with each element containing a filename. As far as I can tell, it’s returning a string with each element contained within curly-brackets {} like so:
{C:UsersBVCAPFile1.txt} {C:UsersBVCAPFile2.txt}
This is what I get if I try print(files). It looks like it’s formatted like a list of some sort, but it seems to just be a string. Am I doing something wrong, or is the output of this function actually a string formatted like a list of files, which I need to split up by myself.

This is actually a bug on the Windows version that has been present since around the 2.6 release of Python. You can find the issue on their tracker, and there’s a workaround in the comments (I have not personally tried this workaround because I’m on Linux, which returns a proper tuple). I’m not aware of a fix since then, and the issue has not been marked as closed/resolved.
The suggested workaround in the comment is essentially to do this:
master = Tk() files = askopenfilenames(initialdir="C:\Users\BVCAP\Videos", title="Select files") files = master.tk.splitlist(files) #Possible workaround self.num_files.set(len(files))
