 1 import random,time
 2 list1=0
 3 list2=0
 4 for i in range(1,4):
 5     print(‘-------------当前是第‘ + str(i) + ‘局‘ + ‘-------------‘)
 6     time.sleep(2)
 7     list1=random.randint(0,100)
 8     list2=random.randint(0,100)
 9     a1=random.randint(0,50)
10     a2=random.randint(0,50)
11     while list1>0 and list2>0:
12         # while执行循环体，并会多次重复测试直到测试为假后才执行循环后的其它语句。
13         list1=list1-a2
14         list2=list2-a1
15         print(‘list1剩余数值：‘+str(list1))
16         print(‘list2剩余数值：‘ + str(list2))
