This is my second day with perl. I've worked mainly in java, ruby, and php. I know this is pretty basic, but if I have a string with a bunch of tabs and newlines, and I want to split it into a list with the token being either a \t or a \n, how would I do that?

This is actually really easy - you just call split, using "\t" or "\n" as arguments. If you want to split on either of them, use a regular expression as your first argument to split.

I figured that was how you would do it, but I don't know how to make the split method take a regex.
CODE
data.split("[\t\n]")
only produces a list with one element. How should the split statement look?

split will take a regex if you pass it in as a regex instead of a string - like so:
CODE

split(/[\t\n]/, $string);

For more information, you may want to read the documentation on split.

I just realized I've been talking about perl. I meant to say python
