convert string to dictionary in python

Question

How do i convert a string to python dictionary? I get the string in the following format as input from different application.

{ foo1 = [ "User1", "User2" ] bar1 = [ "User3", "User4" ] }
{ foo2 = [ "User5", "User6" ] }
{ foo3 = ["User7", "User8"] bar2 = [ "User9", "User10", "User 11" ] moo = ["User12"] }

I have to convert to the following format in python dictionary.

{ "foo1" : "User1,User2" , "bar1" : "User3,User4" }
{ "foo2" : "User5,User6" }
{ "foo3" : "User7" , "bar2" : "User9,User10,User 11" , "moo" : "User12"}

Can you fix the output of that different application so it would use a well-supported text-based serialization format (e.g. JSON, YAML) as it's output instead of it's own, home-cooked one? — juanpa.arrivillaga

Also - the use of comma as a separator doesn't seem consistent between 1st and 3rd example... What's going on there? — Jon Clements

And bar2 really gets scrunched into one string that's comma separated? Seems odd... — Jon Clements

So you have a third-party application that appears to be supplying you the data in a custom format, and does not support JSON or YAML or anything else conventional.

If that format is indeed completely custom without any serializers/deserializers already available, you have no choice but to write your own parser.

Thus your question becomes “How to easily create a parser for custom formatted data in Python?”
