elif在python中啥意思_python中的elif是什么意思

elif是else if的简写。else和elif语句也可以叫做子句，因为它们不能独立使用，两者都是出现在if、for、while语句内部的。else子句可以增加一种选择；而elif子句则是需要检查更多条件时会被使用，与if和else一同使用。

实例：people = 30

cars = 40

buses = 15

if cars > people:

print( "We should take the cars.")

elif cars < people:

print ("We should not take the cars.")

else:

print ("We can't dicide.")

if buses > cars:

print ("That's too many buses.")

elif buses < cars:

print ("Maybe we could take the buses.")

else:

print ("We still can't decide.")

if people > buses:

print ("Alright, let's just take the buses.")

else:

print ("Fine, let's stay home then.")
