I'm sure you can resolve that one yourself. You have

obj[key] = float_value

Now you want to format the float value as a string showing a decimal number.
So all you need to change is the righthand side. If it helps write it in two 
lines:

some_string = ... expression involving float_value ...
obj[key] = some_string
