Question

what is the correct way :

def my_func():
  return {'key1': val1, 'key2': val2}

or

def my_func():
  return
  {
    'key1': val1, 
    'key2': val2
  }

The second way seems more readable (especially when there is a lot of keys values, or nested objects) but I’m not sure the blank after return will work in every case

edit:

After some answers, I would suggest this :

def my_func():
  return {'key1': val1, 
          'key2': val2}

which seems to be the most consistent

Answer 1

For short dictionaries, the first one is OK, the second one won’t work as expected (returns None). For longer ones, I would prefer something like

def my_func():
    return {'key1': val1,
            'key2': val2,
            'key3': val3,
            'key4': val4,
           }
