Renaming of files in OS directory
Hi, all, I am writing a program that renames files inside OS directories the user provides. I am at the early stage of writing it and I encountered some problems. Below is my code. There is an error i received when i run this code. The error is, WindowsError: [Error 123] The filename, directory name, or volume label syntax is incorrect. Hope you guys could help. import os, glob def fileDirectory(): #Asks the user for a file root directory fileroot = raw_input(Please input the file root directory \n\n) print fileroot #Returns a list with all the files inside the file root directory os.listdir(fileroot) fileDirectory() -- http://mail.python.org/mailman/listinfo/python-list

What is the actual string you pass to os.listdir after you got it from the user? You could print repr(fileroot) to find out. My tentative guess is that maybe Windows doesn't like newlines in file names (I know UNIX allows them, but they're still usually a bad idea) and maybe you string ends with a newline. -- http://mail.python.org/mailman/listinfo/python-list

The string i passed to os.listdir is the string i keyed inside fileroot under the raw_input? -- http://mail.python.org/mailman/listinfo/python-list

Okay, maybe you've already understood the problem now, but in case you haven't: 'C:\\' is no valid file name. The quotes () are part of what you're passing to the OS here, which you don't want. Just enter the file name without quotes. (or, if you really want quoting for some reason, you could manually strip the quotes, or use the shlex module. import os, glob def fileDirectory(): # Ask user for file directory input fileroot = raw_input(Input) print repr(fileroot) #Returns a list with all the files inside the file root directory( The error occurs here ) os.listdir(fileroot) fileDirectory() -- http://mail.python.org/mailman/listinfo/python-list
