I have an idea to improve indenting guidelines for dictionaries for better readability: If a value in a dictionary literal is placed on a new line, it should have (or at least be allowed to have) a n additional hanging indent.
Below is an example: mydict = {'mykey': 'a very very very very very long value', 'secondkey': 'a short value', 'thirdkey': 'a very very very ' 'long value that continues on the next line', } As opposed to this IMHO much less readable version: mydict = {'mykey': 'a very very very very very long value', 'secondkey': 'a short value', 'thirdkey': 'a very very very ' 'long value that continues on the next line', } As you can see it is much harder in the second version to distinguish between keys and values.
