Python-练习 while 和for 循环

 # while 循环
 age = 56count = 0
 while count < 3 :
     guess_age=int(input('输入年龄：'))
     if guess_age == age:
         print('猜到了')
         break
     elif guess_age > age:
         print('猜大了')
     else:
         print('猜小了')
     count +=1
     if count==3:
         shuru=input('还玩吗（Y/N）')
         if shuru != 'n':
             count =0
 else:
     print('以输入3次，告辞') '''

 #从0开始循环，最大到10，步数是2
 for i in range(0,10,2):
     print(i)

 for i in range(10):
     print('---',i)
     for j in range(10):
         print(j)
         if j >5:
             break
