AttributeError：'list'对象没有属性'item'询问

Question

我收到了意外的错误。我意识到有些帖子有类似的错误，但是无法理解答案，或者无法将其与我的案例（词典）联系起来。

我想为输入文件的每一行计算相似性分数，并且在每次迭代中（即输入文件的每一行）都会将分数的前20个值存储在字典中。

以下是我的代码：

import sys 
from cx_Freeze import setup, Executable 

includefiles = ['Arcade Funk.mp3', 'game over.wav', 'FrogTown.wav','pixel ufo.png','introBackground.png','pixel playButton.png','pixel instructionButton.png','pixel playButtonHighlighted.png','pixel instructionButtonHighlighted.png','instructionPage.png','crashBackground.png','space background long.png','pixel earth.png','pixel asteroid.png', 'pixel icon.png','Montserrat-ExtraBold.otf','Montserrat-Bold.otf','arial.ttf'] 
includes = [] 
excludes = ['Tkinter'] 
packages = ['pygame'] 
build_exe_options = {'includes':[includes],'packages':[packages], 'excludes':[excludes], 'include_files':[includefiles]} 

base = None 
if sys.platform == 'win64': 
    base = 'Win64GUI' 
elif sys.platform == 'win32': 
    base = 'Win32GUI' 

setup( name = 'Earth Invaders', 
     version = '0.1', 
     author = 'Victor Olawale-Apanpa', 
     description = 'Slider Game: Space', 
     options = {'build_exe': [build_exe_options]}, 
     executables = [Executable('EarthInvaders.py', base=base)] 
) 

这是错误

Traceback (most recent call last): 
    File "C:/Users/Vix_Ox/Desktop/Earth Invaders/setup.py", line 21, in <module> 
executables = [Executable('EarthInvaders.py', base=base)]

for (opt, val) in cmd_options.items(): 
AttributeError: 'list' object has no attribute 'items'

看起来你一直在关注the documentation罚款。

我认为这个问题是第20行的一些额外的方括号：[build_exe_options]应该是build_exe_options。该变量预计会成为一个字典，但它会得到一个列表，从而导致错误。

setup( name = 'Earth Invaders', 
     version = '0.1', 
     author = 'Victor Olawale-Apanpa', 
     description = 'Slider Game: Space', 
     options = {'build_exe': build_exe_options}, 
     executables = [Executable('EarthInvaders.py', base=base)] 
) 

您也可能会发现，你必须追溯应用此到一个较早的线，因为它们在列表中已经封装在声明时：

build_exe_options = {'includes':includes,'packages':packages, 'excludes':excludes, 'include_files':includefiles}
