What is the best way of writing code?

Question

I often write stupid codes like

from secrets import token_hex as t
from random import randint as r
print(''.join(list(map(lambda x : x.upper() if r(0,2) else x , list(t(24))))))#generates 24 digit key with uppercase and lowercase letters with numbers

Because I don't want codes to be redundant and make my code of 1000 lines. I often lose track of everything. How can i write them in a understandable way without silly comments or variables?

Answer 1

Long codes are not difficult to maintain, if they are good...

Answer 2

Use proper, meaningful names and correct formatting.

Answer 3

For python you can check out PEP: https://www.sololearn.com/learn/Python/2483/

Answer 4

~ swim ~ I am expecting that you will help me to write code which is neither long nor short. You can tell me what to avoid , how to write, some useful resources, etc. Long codes are hard to maintain and short ones are hard to understand.
