    When you are upturn in your career from beginner to experienced in programming world, your team will start looking at ‘how you are writing?’ Here the responsibility piling up.
 
    Okay, how to code in better standard? - PEP 8: It is a standard, the python community defined to follow by any programmer across the globe.
Are they huge, hard to remember? - May be, yes. But, by experience we can adopt to this convention.

dummyDict={}
for item in (1,2,3,):
           dummyDict[item]=item

print(dummyDict)
------------------------------------------------------ 
 
Just assume that you have written the above program. If you are experienced enough, finding the flaw in the formatting is an easy task.
For ex:
  1. Any line should not exceed 72 characters
  2. have to apply space before and after any operator( = , == + )
  3. For indentation we can go up to 4 spaces
  4. (1,2,3,)-> Here, the trailing comma(,) is not needed, also the space after , is advisable.

step 1: Installation: pip install black
step 2: black {source_file_or_directory}(black sample.py)

And, the out come of the above program after applying black is below,
