我有一个像这样的元组列表:
ListOfTuples = [(var1,var2,var3,var4,var5),
(var6,var7,var8,var9,var10),
(var11,var12,var13,var14,var15),
(var16,var17,var18,var19,var20)]
我想交换两个元组,即列出如下列表:
ListOfTuples = [(var1,var2,var3,var4,var5),
(var6,var7,var8,var9,var10),
(var16,var17,var18,var19,var20)
(var11,var12,var13,var14,var15)]
我尝试了以下尝试失败:
ListOfTuples[2], ListOfTuples[3] = ListOfTuples[3] , ListOfTuples[2]
有谁能告诉我该怎么做?

您的代码对我来说很好。我也尝试过下面的代码,它对我有用:
data = [(1,2,3), (3,4,5), (5,6,7), (7,8,9)]
data[2:] = reversed(data[2:])
>>> [(1, 2, 3), (3, 4, 5), (7, 8, 9), (5, 6, 7)]
我已尝试以下列方式使用条件:
data = [(1,2,3), (3,4,5), (5,6,7), (7,8,9)]
for i,x in enumerate(data):
if i+1 < len(data) and x[0] < data[i+1][0]:
data[i], data[i+1] = data[i+1], data[i]
>>> [(3, 4, 5), (5, 6, 7), (7, 8, 9), (1, 2, 3)]
答案 1 :(得分:-2)
temp = ListOfTuples[2]
ListOfTuples[2] = ListOfTuples[3]
ListOfTuples[3] = temp
