while循环

while循环 (难点)
    while 条件:
        循环体(break, continue)

while True:
    content = input("请输入你要喷的内容, 输入Q退出")
    if content == "Q":
        # 退出程序 打断循环
        break # 直接跳出循环
    print("你对打野说:", content)

 if True:
     print("娃哈哈")

最多喷三次
count = 1
while count <= 3:

    # count = 1  # 次数, 死循环
    content = input("请输入你要喷的内容")
    print("你要对上单说:", content)

    # 改变count
    count = count + 1

continue
while True:
    content = input("请输入你要喷的内容, 输入Q退出")
    if content == "":
        continue # 停止当前本次循环. 继续执行下一次循环  不会彻底中断循环.
    if content == "Q":
        # 退出程序 打断循环
        break # 直接跳出循环
    print("你对打野说:", content)

能够让循环退出: 1. break  2. 改变条件

 continue  停止当前本次循环. 继续执行下一次循环
 break  彻底的干掉一个循环

count = 1
while count <= 100:
    print(count) # 1
    count = count + 1

sum = 0                 # sum: 0 + 1 + 2 + 3 + 4....99 + 100
count = 1               # count: 1, 2, 3, 4, 99,100, 101
while count <= 100:
    sum = sum + count  # 累加运算
    count = count + 1
print(sum)

count = 1
while count <= 100:
    print(count)
    count = count + 2

count = 1
while count <= 100:
    if count % 2 == 1:
        print(count)
    else:
        print("偶数....")
    count = count + 1
