在python中生成列表时获取列表对象附加的消息内置方法

Question

我正在尝试构建一个列表，其中包含列表中的第二个元素。我第一次抓取了一些链接并存储在links_2016中

for i in links_2016:
    parsed = urlparse.urlparse(i)
    path = parsed[2] 
    pathlist = path.split("/")
    list_pathlist.append(pathlist)

#get the months
months = []
for i in range(0,44): #there are 44 elements in list_pathlist
    list_pathlist[i][2] #get the second element 
    months.append

但是，当我打印月份时，我会在列表中得到内置的方法消息：

'06'
<built-in method append of list object at 0x103c85170>
'06'
<built-in method append of list object at 0x103c85170>

在这之后，当我做print months时，我只得到[]，这意味着结果有问题。

我还需要计算月份列表中的元素，所以我想学习如何解决这个问题。

希望现在起作用了

for i in links_2016:
    parsed = urlparse.urlparse(i)
    path = parsed[2] 
    pathlist = path.split("/")
    list_pathlist.append(pathlist)

#get the months
months = []
for i in range(0,len(list_pathlist)): #there are 44 elements in list_pathlist 
    months.append(list_pathlist[i][2]) #you are actually getting the third item
                                       #since list indice start at 0, if you want the second item do [1]
print(months)

要计算月份列表中的元素，请执行len(months)
