1）编写一个程序来获取以下输出：
1 2 3 4 5 5 4 3 2 1
no = 1 top = 5 direction = 1 while no>0: print(no,end= ' ') if no == top: print(no,end=' ') direction = -1 no = no + direction
输出：
1 2 3 4 5 5 4 3 2 1
使用随机模块：
2) 猜数字游戏：
程序将一直运行直到我们猜出数字
import random system_no = random.randint(1,20) while true: guess = int(input("enter the no. ")) if guess == system_no: print("hurray! i got the number!! ") break elif guess > system_no: print("your guess is too high! ") else: print("your guess is too low! ")
输出：
enter the no. 5 your guess is too low! enter the no. 7 your guess is too low! enter the no. 10 your guess is too low! enter the no. 12 hurray! i got the number!!
3) 数字中最大的数字：
no = int(input("enter no. ")) max_no = 0 while no>0: rem = no%10 if rem>max_no: max_no = rem no//=10 print(max_no)
输出：
enter no. 452 5
所以在 452 中，5 是数字中最大的数字。
任务：
1) 查找数字中最小的数字：
no = int(input("enter no. ")) min_no = 9 while no>0: rem = no%10 if rem<min_no: min_no=rem no//=10 print(min_no)
输出：
enter no. 452 2
2) 判断所有数字是否相等
no=input("enter the no. ") num=1 while num <len(no): if no[num]==no[0]: print("all digits are equal") break num+=1 else : print("not equal")
输出：
1)Enter the no. 4444 All digits are equal 2)Enter the no. 46562 Not equal
