Python "best formatting practice" for lists, dictionary, etc

Question

I have been looking over the Python documentation for code formatting best practice for large lists and dictionaries, for example,

something = {'foo' : 'bar', 'foo2' : 'bar2', 'foo3' : 'bar3'..... 200 chars wide, etc..} 

or

something = {'foo' : 'bar',              'foo2' : 'bar2',              'foo3' : 'bar3',              ...              } 

or

something = {              'foo' : 'bar',              'foo2' : 'bar2',              'foo3' : 'bar3',              ...              } 

How do I handle deep nesting of lists/dictionaries?

Answer 1

My preferred way is:

something = {'foo': 'bar',              'foo2': 'bar2',              'foo3': 'bar3',              ...              'fooN': 'barN'}
