標籤：python基礎   inpu   print   ==   while迴圈   三次   bsp   and   nbsp   

1、使用while迴圈輸入 1 2 3 4 5 6     8 9 10

count = 1while count< 11:    if count == 7:           count+=1        continue    print(count)    count+=1

 

2、求1-100的所有數的和

counts = 1num = 0while counts <101:    num +=counts    counts+=1print(num)

　　

3、輸出 1-100 內的所有奇數

counte = 1while counte < 101:    if counte % 2 == 1:        print(counte)    counte+=1

　　

4、輸出 1-100 內的所有偶數

counte = 1while counte < 101:    if counte % 2 != 1:        print(counte)    counte+=1

　　

5、求1-2+3-4+5 ... 99的所有數的和

counte = 1num = 0num1 = 0while counte < 100:    if counte % 2 != 1:        num += -counte    else:        num1 += counte    counte+=1print(num+num1)

　　

6、使用者登陸（三次機會重試）

count = 0while count<3:    count +=1    username = input("username:")    password = input("password:")    if username == ‘alex‘ and password == ‘123456‘:        print(‘登陸成功！‘)        break    else:        print(‘請重試！‘)
