Ok lost on why my python script is screwing up my fille ops

So I'm trying to write a python script to sort and move files based on the format name, and it works up to the moving part. I found out that it is because python has issues with the file path.

Code: Select all
for dirFile in os.listdir(currentFolder):
            #pulls the format type out of the file
            fileFormat = dirFile[dirFile.index(".")+1:]
            #moves the file to it's new destination
            #shutil.move(currentFolder+slash+dirFile, currentFolder+slash+formatArray[fileFormat])
            print currentFolder+slash+formatArray[fileFormat]+slash+"Broken part"
        except ValueError:
        except KeyError:
            logFile.write(timeStamp()+"Unknown file format "+fileFormat+" add to "+sourceFile+" to fix"+"\n")
        except shutil.Error:
            logFile.write(timeStamp()+"Can not move file "+dirFile+"\n")

Expected:/media/usbstick/music/Broken part
Obtained:/Broken partick/music

This is a problem cause I can't transfer files without them screwing up.

Try printing the contents of each variable separately. Also if you are passing "currentfolder" I can't see how it can be empty. That is basic string manipulation and Python can do that fine.

It looks as though the entries in formatArray might have some odd characters in.

A couple of Python tips may help:

1) look at the docs for os.path.split(), os.path.join() and friends. They're usually the right way to manipulate file names.

2) if you don't understand some output, try

print repr( something )

repr() will show things in their Python language representation, which is very useful for seeing odd characters in strings.
