如何使用 configparser 更新值 python .ini 文件

如何解决如何使用 configparser 更新值 python .ini 文件

我正在编写一个代码，我可以将所有其他应用程序放入其中（例如集线器）。我想将我的进度保存到 .ini 文件中。我使用了 .set 命令。我还在退出函数中添加了一个保存写入循环，但它不起作用。它显示此错误：

Traceback (most recent call last):
  File "C:\Users\User\Desktop\os\interface.py",line 20,in <module>
    apps = int(config['DEFAULT']['apps'])
  File "C:\Users\User\AppData\Local\Programs\Python\python39\lib\configparser.py",line 1254,in __getitem__
    raise KeyError(key)
KeyError: 'apps'

savefile.ini

[DEFAULT]
apps = blue
allapps = setings,powerbrowser
games = 0
allgames = 
coins = 0
image = 0
toolbar_color = black

yborder1 = 2

main.place(x=xmain,y=ymain)
tool.place(x=0,y=815)
background.pack(expand=True)
date.place(x=1370,y=10)
border1.place(x=60,y=yborder1)
shutdown.place(x=12,y=5)




root.mainloop()

请帮帮我。也许有更好的方法。（我英语不好所以可能会有拼写错误）。

解决方法

根据python documentation，代码的用法：

from configparser import ConfigParser

config = ConfigParser()
config.read('savedata/savefile.ini')
apps = int(config['DEFAULT']['apps'])

如果正在解析的文件有效，则正确。我建议输出数据并查看它是否正确解析：

from configparser import ConfigParser

config = ConfigParser()
config.read('savedata/savefile.ini')
print(config.sections())

输出应至少包含“DEFAULT”。如果没有，则说明解析不正确，因此请确保给定的文件名有效。
