Changing ' to " in printed representation of dictionaries

[Burton Samograd]

Hello,

I was wondering if there was a way to change the quote character for
keys in string representation of dictionaries, so that they will be JSON
equivalent. For example:
'{ "x": 1, "y": 2 }' # JSON and python compatible

So the question is, is there an automatic way to tell python to use "
instead of ' when doing a repr of lists?

Thanks.
