while-else if

while-else

1、break立即打断循环并且不再执行else

count = 0
while count <= 5:
    count += 1
    if count == 3:
        break
    print("loop",count)
else:
    print("循环执行完了")
print("end")

2、while循环后会执行else

count = 0
while count <= 5:
    count += 1
    if count == 3:
        pass
    print("loop",count)
else:
    print("循环执行完了")
print("end")

 

 if

i = 10
if i==10:
    print("11")
if i>5:
    print("22")

i = 10
if i==10:
    print("11")
elif i>5:
    print("22")

都是if的话两个分支都会走

elif满足第一个条件就不会走elif
