7.17 作业

1. 使用while循环输出1 2 3 4 5 6 8 9 10

i = 0 while i<10: i+=1 if i == 7: continue print(i,end='')

2. 求1-100的所有数的和

s = 0 t = 0 while s<100: s+=1 t+=s print(t)

3. 输出 1-100 内的所有奇数

s = 0 while s<100: s+=1 if s % 2 == 1: print(s,end=' ')

4. 输出 1-100 内的所有偶数

s = 0 while s<100: s+=1 if s % 2 == 0: print(s,end=' ')

5. 求1-2+3-4+5 ... 99的所有数的和

s = 0 t = 0 while s<99: s+=1 if s%2==1: t+=s if s%2==0: t-=s print(t)

6. 用户登陆（三次机会重试）

id1 = 'wzh' pwd1 = '123' c = 1 while c<4: c+=1 id = input('please enter id:') password = input('please enter password:') if id == id1 and password == pwd1: print('wellcom!') break

7：猜年龄游戏

要求： 允许用户最多尝试3次，3次都没猜对的话，就直接退出，如果猜对了，打印恭喜信息并退出

right = 18 for i in range(3): i += 1 s = input('please enter the age as your mean:') if int(s) == right: print("your enter's age is right !!!") break

8：猜年龄游戏升级版(选做)

要求： 允许用户最多尝试3次 每尝试3次后，如果还没猜对，就问用户是否还想继续玩，如果回答Y或y, 就继续让其猜3次，以此往复，如果回答N或n，就退出程序 如何猜对了，就直接退出

right = 18 while True: t = input('do you want to play the game? please enter y/Y or n/N:') if t == 'y' or t == 'Y': # 更改打印字体颜色，后面一样 print('\033[1;35;0m game beginning!\033[0m') for i in range(3): i += 1 s = input('please enter the age as your mean:') if int(s) == right: print('\033[1;35;0m your enter\'s name is right !!! \033[0m') break else: print('\033[1;35;0m your enter\'s age is wrong\033[0m') else: print('\033[1;35;0m game over!\033[0m') break

9.for循环打印99乘法表

for i in range(1,10): print(end="\n") for j in range(1,i+1): print(str(i)+'*'+str(j)+'='+str(i*j),end=' ')

10.for循环打印金字塔:

s = input('please enter the pyramid\'s length(1-50):') for i in range(int(s)): print(f'{"*"*(2*i+1): ^100}')
