python while循环

while循环格式

while 条件:
            循环体(break, continue)

例子

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)

count = 1  # 次数
while count <= 3:
    content = input("请输入你要喷的内容")
    print("你要对上单说:", content)
    # 改变content
    count = count + 1

  计算1-100的和

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)

输出1-100所有奇数或偶数

奇数

num3 = 1
while num3 <= 100:
    if num3 % 2 == 1:
        print(num3)
    num3 += 1

偶数

num3 = 1
while num3 <= 100:
    if num3 % 2 == 0:
        print(num3)
    num3 += 1
