python while循環

while循環格式

while 條件:
            循環體(break, continue)

例子

while True:
    content = input("請輸入你要噴的內容,輸入Q退出")
    if content == "Q":
        # 退出程序 打斷循環
        break  # 直接跳出循環
    print("你對打野說:", content)

 

count = 1  # 次數
while count <= 3:
    content = input("請輸入你要噴的內容")
    print("你要對上單說:", content)
    # 改變content
    count = count + 1

  計算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   # 累加運算
    count = count + 1
print(sum)

 

輸出1-100所有奇數或偶數

奇數

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

偶數

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