python 基礎(練習題)

1.使用while 循環輸入 1 2 3 4 5 6 7 8 9 10

num = 1
while num < 11:
    print(num)
    num += 1

2.求1-100的全部數的和num = 1sum = 0while num <101:    sum += num    num += 1print(sum)3.輸出1-100內的全部奇數num = 1while num < 101:    temp = num % 2    if temp == 0:        print(num)    num += 1    4.輸出1-100內的全部偶數sum = 1while sum < 100:    tang = sum % 2    if tang != 0:       print(sum)    sum += 1    5.模擬用戶登陸，容許用戶錯三次（帳號爲tang，密碼123456）sum = 0while sum < 3:   user = input("請輸入帳號：")   password = input("請輸入密碼：")   if user == "tang":      if password == "123456":         print("登陸成功")         break      else:         print("密碼錯誤")   else:      print("沒有此用戶")   sum += 1
