如下的例子中，将二维数组按照第二维的降序进行排序
### Prepare the list
complist = []
tmpFactor= []
tmpFactor.append("[Action-1]")
tmpFactor.append(3)
complist.append(tmpFactor)
tmpFactor= []
tmpFactor.append("[Action-2]")
tmpFactor.append(5)
complist.append(tmpFactor)
tmpFactor= []
tmpFactor.append("[Action-3]")
tmpFactor.append(2)
complist.append(tmpFactor)
tmpFactor= []
tmpFactor.append("[Action-4]")
tmpFactor.append(1)
complist.append(tmpFactor)
tmpFactor= []
tmpFactor.append("[Action-5]")
tmpFactor.append(8)
complist.append(tmpFactor)
tmpFactor= []
tmpFactor.append("[Action-6]")
tmpFactor.append(4)
complist.append(tmpFactor)
tester=0
lcount = len(complist)
### Sort desc
for x in range(lcount-1):
for y in range(x+1,lcount):
print("")
if complist[x][1] < complist[y][1]:
complist[x],complist[y]=complist[y],complist[x]
print("exchanged")
else:
tester=1 ## Just to make if-else to end easily
print(complist)
tester=0 ## Just to make the outer for cycle to end easily
print (complist)
运行结果如下：
exchanged
[['[Action-2]', 5], ['[Action-1]', 3], ['[Action-3]', 2], ['[Action-4]', 1], ['[Action-5]', 8], ['[Action-6]', 4]]
[['[Action-2]', 5], ['[Action-1]', 3], ['[Action-3]', 2], ['[Action-4]', 1], ['[Action-5]', 8], ['[Action-6]', 4]]
[['[Action-2]', 5], ['[Action-1]', 3], ['[Action-3]', 2], ['[Action-4]', 1], ['[Action-5]', 8], ['[Action-6]', 4]]
exchanged
[['[Action-5]', 8], ['[Action-1]', 3], ['[Action-3]', 2], ['[Action-4]', 1], ['[Action-2]', 5], ['[Action-6]', 4]]
[['[Action-5]', 8], ['[Action-1]', 3], ['[Action-3]', 2], ['[Action-4]', 1], ['[Action-2]', 5], ['[Action-6]', 4]]
[['[Action-5]', 8], ['[Action-1]', 3], ['[Action-3]', 2], ['[Action-4]', 1], ['[Action-2]', 5], ['[Action-6]', 4]]
[['[Action-5]', 8], ['[Action-1]', 3], ['[Action-3]', 2], ['[Action-4]', 1], ['[Action-2]', 5], ['[Action-6]', 4]]
exchanged
[['[Action-5]', 8], ['[Action-2]', 5], ['[Action-3]', 2], ['[Action-4]', 1], ['[Action-1]', 3], ['[Action-6]', 4]]
[['[Action-5]', 8], ['[Action-2]', 5], ['[Action-3]', 2], ['[Action-4]', 1], ['[Action-1]', 3], ['[Action-6]', 4]]
[['[Action-5]', 8], ['[Action-2]', 5], ['[Action-3]', 2], ['[Action-4]', 1], ['[Action-1]', 3], ['[Action-6]', 4]]
exchanged
[['[Action-5]', 8], ['[Action-2]', 5], ['[Action-1]', 3], ['[Action-4]', 1], ['[Action-3]', 2], ['[Action-6]', 4]]
exchanged
[['[Action-5]', 8], ['[Action-2]', 5], ['[Action-6]', 4], ['[Action-4]', 1], ['[Action-3]', 2], ['[Action-1]', 3]]
exchanged
[['[Action-5]', 8], ['[Action-2]', 5], ['[Action-6]', 4], ['[Action-3]', 2], ['[Action-4]', 1], ['[Action-1]', 3]]
exchanged
[['[Action-5]', 8], ['[Action-2]', 5], ['[Action-6]', 4], ['[Action-1]', 3], ['[Action-4]', 1], ['[Action-3]', 2]]
exchanged
[['[Action-5]', 8], ['[Action-2]', 5], ['[Action-6]', 4], ['[Action-1]', 3], ['[Action-3]', 2], ['[Action-4]', 1]]
>>> tester=0 ## Just to make the outer for cycle to end easily
>>> print (complist)
[['[Action-5]', 8], ['[Action-2]', 5], ['[Action-6]', 4], ['[Action-1]', 3], ['[Action-3]', 2], ['[Action-4]', 1]]
