The ternary operation of Python

The ternary operation of Python is to first output the result and then determine the condition. The format is as follows:

>>> def f (x, Y):
return x-y if x>y else abs (x-y)
#如果x大于y就返回x-y value, otherwise returns the absolute value of X-y

>>> f (3,4) #3 <4, does not meet the IF condition, it returns the absolute value inside the Else
>>> F (4,3)
>>> def f (x, Y):
Return 1 if X>y else-1
#如果x大于y就返回x-y value, or return-1
>>> f (3,4) #3小于4, return-1
-1
>>> f (4,3) #4大于3, return 1
>>>
