More than one if-else in single line, how to interpret them?

Well I certainly Understand if-else that are return in single line like

return 0 if x==y else 1

Which translate to

if x==y:
return 0
return 1

I am confused about those statements where if-else occurs multiple time in one line like

def _cmp(x, y):
return 0 if x == y else 1 if x > y else -1

How to interpret and understand multiline if-else statements.

Introducing parentheses makes it easier to understand.

0 if x == y else 1 if x > y else -1

must be parsed as

0 if x == y else (1 if x > y else -1)
