重新编码命名的元组

Question

输入：

import mouse 
import pickle 
from collections import namedtuple 

#https://github.com/boppreh/keyboard/blob/master/keyboard/mouse.py 

#from ._mouse_event import ButtonEvent, MoveEvent, WheelEvent, LEFT, RIGHT, 
MIDDLE, X, X2, UP, DOWN, DOUBLE 


ButtonEvent = namedtuple('ButtonEvent', ['event_type', 'button', 'time']) 
WheelEvent = namedtuple('WheelEvent', ['delta', 'time']) 
MoveEvent = namedtuple('MoveEvent', ['x', 'y', 'time']) 

with open ('outfile', 'rb') as fp: 
    itemlist = pickle.load(fp) 

#print (type (itemlist)) 
print (itemlist[:3]) 

z=0 
xx=50 
yy=10 
itemlist2=[] 

for i in itemlist: 
    old_event = itemlist[z] 
    new_event = MoveEvent(x=xx, y=yy, time=old_event.time) 
    itemlist2.append(new_event) 
    z=z+1 
    xx=xx+1 
    yy=yy+1 
print() 

print (itemlist2[:3]) 

print (type (itemlist)) 
print (type (itemlist[0])) 
print (type (itemlist[0][0])) 

print() 

print (type (itemlist2)) 
print (type (itemlist2[0])) 
print (type (itemlist2[0][0])) 

输出：

[MoveEvent(x=1369, y=162, time=1504533266.029788), MoveEvent(x=1358, y=165, time=1504533266.0377884), MoveEvent(x=1350, y=167, time=1504533266.045789)] 

[MoveEvent(x=50, y=10, time=1504533266.029788), MoveEvent(x=51, y=11, time=1504533266.0377884), MoveEvent(x=52, y=12, time=1504533266.045789)] 
<class 'list'> 
<class 'mouse._mouse_event.MoveEvent'> 
<class 'int'> 

<class 'list'> 
<class '__main__.MoveEvent'> 
<class 'int'> 

新来这里 - 蟒蛇 当我重新组装命名元组的名单为itemlist2我需要保持 -class mouse._mouse_event.MoveEvent - - 不知道该怎么做

我想我也可以尝试编辑'itemlist'直接if这是可能的

时打印的清单长得一模一样（除了变更值）

Answer 1

你创造了文件的新MoveEvent namedtuple类型：

MoveEvent = namedtuple('MoveEvent', ['x', 'y', 'time']) 

如果你想使用原来，你需要使用mouse._mouse_event.MoveEvent或以上将其重命名：

MoveEvent = mouse._mouse_event.MoveEvent 

因为mouse.py包括这一行：

from ._mouse_event import ButtonEvent, MoveEvent, WheelEvent, LEFT, RIGHT, MIDDLE, X, X2, UP, DOWN, DOUBLE 

你或许可以使用此代码：

import mouse 
from mouse import MoveEvent
