Python 3语法学习之练习代码及输出37

#Python中的两种循环：for循环和while循环
#for循环在可迭代的序列被穷尽时停止
#while循环在条件不成立时停止，即只要……条件成立，就一直做……
while 1 < 3:
    print('1 is smaller than 3')
#永远为True的循环，称之为死循环，Ctrl+C强制停止运行

#赋值变量，计数目的，初始值为0
count = 0
#while循环
while True:
    print('Repeat this line!')
    count = count + 1 #每打印一行，对count加1并重新赋值给count
    if count == 5: #判断count当前是否为5，是则终止while循环
        break #关键词
