Is there a PEP suggestion for the use of the ternary operator?

Answer 1

PEP8 does not specifically mention the ternary operator, but it contradicts with the principle that each statement should be written in a separate line.

- find "compound statements"

Answer 2

yeah as long as it only contains one if statement:
x = "Enough" if len(lst) > 5 else "Need more"

However, if it contains multiple if statements then that makes it hard to read and therefore should be avoided.
