I get nervous when I read instructions like this. It sounds too much like voodoo: "Do this, because it works, never mind how or under what circumstances, just obey or the Things From The Dungeon Dimensions will suck out your brain!!!" Sorry Fredrik :-) When you read a Windows text file using "r" mode, what happens to the \r immediately before the newline? Do you have to handle it yourself? Or will Python cleverly suppress it so you don't have to worry about it? And when you write a text file under Python using "w" mode, will the people who come along afterwards to edit the file in Notepad curse your name? Notepad expects \r\n EOL characters, and gets cranky if the \r is missing. How does this behaviour differ from "universal newlines"? -- Steven -- http://mail.python.org/mailman/listinfo/python-list
