[python] 파이썬에서 여러 줄로 된 dict을 형식화하는 올바른 방법은 무엇입니까?

우선, Steven Rumbalski와 같이 “PEP8은이 질문을 다루지 않습니다”라고 말했기 때문에 개인적인 취향의 문제입니다.

나는 당신의 형식 3과 비슷하지만 동일한 형식을 사용하지 않을 것입니다. 여기에 내 이유가 있습니다.

my_dictionary = { # Don't think dict(...) notation has more readability
    "key1": 1, # Indent by one press of TAB (i.e. 4 spaces)
    "key2": 2, # Same indentation scale as above
    "key3": 3, # Keep this final comma, so that future addition won't show up as 2-lines change in code diff
    } # My favorite: SAME indentation AS ABOVE, to emphasize this bracket is still part of the above code block!
the_next_line_of_code() # Otherwise the previous line would look like the begin of this part of code

bad_example = {
               "foo": "bar", # Don't do this. Unnecessary indentation wastes screen space
               "hello": "world" # Don't do this. Omitting the comma is not good.
} # You see? This line visually "joins" the next line when in a glance
the_next_line_of_code()

btw_this_is_a_function_with_long_name_or_with_lots_of_parameters(
    foo='hello world',  # So I put one parameter per line
    bar=123,  # And yeah, this extra comma here is harmless too;
              # I bet not many people knew/tried this.
              # Oh did I just show you how to write
              # multiple-line inline comment here?
              # Basically, same indentation forms a natural paragraph.
    ) # Indentation here. Same idea as the long dict case.
the_next_line_of_code()

# By the way, now you see how I prefer inline comment to document the very line.
# I think this inline style is more compact.
# Otherwise you will need extra blank line to split the comment and its code from others.

# hi this function is blah blah

mydict = dict(
    key1 = 1,
    key2 = 2,
    key3 = 3,
)

dict(rank = int(lst[0]),
                grade = str(lst[1]),
                channel=str(lst[2])),
