What is the proper way to format a multi-line dict in Python?

Question

In Python, I want to write a multi-line dict in my code. There are a couple of ways one could format it. Here are a few that I could think of:

1. mydic         
   
   
           

Answer 1

Since your keys are strings and since we are talking about readability, I prefer :

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