# ture if 判断 else false
result = x if condition else y

eg:
def my_max(x,y):
return x if x>y else y # ture if 判断 else false
bigger = my_max(10,20)
print(bigger)

#（false，ture）[判断]
result = (x, y)[condition]

eg:
def my_max(x,y):
return (y,x)[x>y] # y是false ，x是ture （false，ture）[判断]
bigger = my_max(10,20)
print(bigger)
