Python ternary expression

Question

So here's a simple object creation and assignment using a 1 line ternary expression in Java.

Interval newInterval = previous.end <= current.end ? new Interval(previous.start, current.end : new Interval(previous.start, previous.end)

The python equivalent is,

new_interval = Interval(previous.start, current.end) if previous.end <= current.end else Interval(previous.start, previous.end)

My question is there a more pythonic way to write this?

new_interval = Interval(previous.start, current.end if previous.end <= current.end else previous.end) seems more reasonable to me (in both languages). — Felix Kling

The form I'd like more is probably

new_interval = Interval(previous.start, max(current.end, previous.end))

This is more Pythonic:

start = previous.start
end = max(current.end, previous.end)
new_interval = Interval(start, end)
