Answer 1

here are some general thoughts from me on the subject of one liners.

> many of them are hard to read, difficult to understand and maintain, and it takes a great deal of effort to find errors when debugging them.

> besides being very impressive to look at and challenging to create, one-liners are relatively useless in practice. if you read the coding guidelines from major companies or follow the zen of python you will understand why.

Answer 2

Angela,

Yes you can add more conditions..

See this example..
`age = 16
is_student = False
print("20% discount" if age < 18 and is_student else "Regular price" if age >= 18 else "Invalid age")`

In this example:-
#If the age is less than 18 and the person is a student, it will print "20% discount".

#If the age is 18 or older, it will print "Regular price".

#If the age is neither less than 18 nor 18 or older, it will print "Invalid age".

Answer 3

Here are a couple of ways to handle the logic and reduce the code.

First way: make a decision between the two primary categories (above or below age 18), then check the smaller subdivisions below 18.

print("Regular price" if age>=18 else "20% discount" if is_student else "10% discount")

Second way: select a string to print between the two primary categories, and for the subdivided category use string interpolation with a calculation to modify the output string.

print(("Regular price", f"{10*(1+is_student)}% discount")[age<18])
