The ternary operator is used for inline conditional expressions. It is best used in simple, concise operations that are easily read.
n = 5 "Greater than 2" if n > 2 else "Smaller than or equal to 2" # Out: 'Greater than 2'
The result of this expression will be as it is read in English - if the conditional expression is True, then it will evaluate to the expression on the left side, otherwise, the right side.
Tenary operations can also be nested, as here:
n = 5 "Hello" if n > 10 else "Goodbye" if n > 5 else "Good day"
They also provide a method of including conditionals in lambda functions.
