Python to AS question

Admittedly, I don’t know a lick of Python but I’m trying to convert a small bit to actionscript. One line of code has me flustered though:

[AS]for i in (x, y):
# doStuff[/AS]

where i, x and y are all strings.

Could someone tell me what this is doing and, if possible, suggest an Actionscript alternative?

Thank you for any info/suggestions…
