python RuntimeError: dictionary changed size during iteration

Question

I have obj like this

{hello: \'world\', \"foo.0.bar\": v1, \"foo.0.name\": v2, \"foo.1.bar\": v3}

It should be expand to

{         


        

Answer 1

Like the message says: you changed the number of entries in obj inside of expandField() while in the middle of looping over this entries in expand.

You might try instead creating a new dictionary of the form you wish, or somehow recording the changes you want to make, and then making them AFTER the loop is done.
