Remove -#### in zipcodes

Question

How do I remove the +4 from zipcodes, in python?

I've got data like

85001
52804-3233
Winston-Salem

And I want that to become

85001
52804
Winston-Salem

Answer 1

>>> zip = '52804-3233'
>>> zip[:5]
'52804'

...and of course when you parse your lines from the original data you should insert some kind of rule to distinguish between zipcode to fix and other strings, but I don't know how your data looks like, so I can't help much (you could check if they are only digits and the '-' symbol, maybe?).
