while循环

# 1,初识循环
# while True:
#     print('海草')
#     print('女儿情')
#     print('二泉映月')
#     print('牧马城市')

# 如何终止循环
'''
1,改变条件。
2，break
3,调用系统命令：quit() exit() (不建议使用)
'''

#     print('海草')
#     print('女儿情')

# 四个都打印

# 从 1 ~ 100 利用while循环

# 计数器的概念
# count = 1

# while break continue
# break：循环中遇到break 直接退出循环，
# print(111)

# count = 2
# while count < 101:
#     if count % 2 == 0:
#         print(count)
#     count = count + 1

# continue
# 结束本次循环，继续下一次循环

#while else
