Yep, either way. I personally prefer using forward slashes since there's no way to end an r-string with a single backslash, which is often useful when building a path: # won't work path = r"c:\path\to\some\" open(path + "file") # will work path = "c:/path/to/some/" open(path + "file") ChrisA -- https://mail.python.org/mailman/listinfo/python-list
