练习二十二:python兵乓求比赛顺序练习,关于连个兵乓球队进行比赛

已知有两支兵乓球队进行比赛,每队各出3人:
甲队有a,b,c三人,乙队有x,y,z三人,已抽签决定比赛名单
问题:有人向队员打听比赛名单。a说他不和X比,c说他不和x,z比,程序找出比赛对手

方法一:

  1 list1 = ['a','b','c']
  2 list2 = [0,0,0]
  3 for i in list1:
  4     if i == "c":
  5         list2[list1.index(i)] = 'y'
  6     elif i == "a":
  7         list2[list1.index(i)] = 'z'
  8     else:
  9         list2[list1.index(i)] = 'x'
 10 
 11 for i in range(len(list1)):
 12     print(list1[i],'VS', list2[i],end =' ')
执行结果:
a VS z b VS x c VS y 

方法二:
  1 list1 = ['a','b','c']
  2 for x in list1:
  3     for y in list1:
  4         for z in list1:
  5             if (x!=y) and (y!=z) and (x!=z) and (x!='a') and (x!='c') and (z!='c'):
  6                 print('x VS %s ,y VS %s, z VS %s'%(x,y,z))
执行结果:
x VS b ,y VS c, z VS a
