Is there a shorter way to write this?

discounted_price = original_ticket_price - discount_value

if discounted_price < 0:

    discounted_price = 0

Why would you want a shorter way to write it if you don't mind? Are you golfing or something?

What's the connection to golfing? I just want to learn it the best, shortest way. Thought there might be a better way to write it.

It's just that usually when people ask for the shortest way to write something it's for code golf

Ahh, never heard of that. No, I actually just try to learn it the 'right' way.

Keep asking question then ;) Next time you post here, copy a more sizeable snippet of code, feedbacks will be way more interesting.

Use the built-in max() function:

discounted_price = max(0, original_ticket_price - discount_value)

Python has a syntax for ternary since 2.5.

Syntax for it is a if condition else b, where condition is Truthy or Falsy( see Graipher comment).

You can rewrite your code like:

discounted_price = original_ticket_price - discount_value

discounted_price if discounted_price >= 0 else 0

Personnaly I find it harder to read but it is another way to write your code.

EDIT you can find more info on ternary in this SO post

condition does not have to be a boolean (True or False), a truthy or falsy value is sufficient ([0] and also work), as almost always in Python.
