我正在开发一个小程序,可以用作化学计算器或类似的东西,但在此过程中我遇到了一些麻烦......
在主文件中,我试图从文件 grafika.py 中导入类 Aplikacija,但无论我多么努力,它似乎都不起作用 - 我得到 AttributeError: 'module' object has no attribute 'Aplikacija' .
这可能是初学者的问题,但我已经盯着屏幕看了几个小时,我不知道可能出了什么问题。如果您能帮助我,我将不胜感激:)
PS:请不要介意变量的名称,因为我的母语不是英语...
主文件的(缩短的)代码:
import grafika
from Tkinter import *
root = Tk()
root.title('ChemHelp v0.1')
root.minsize(360, 240)
#root.iconbitmap('mojaikona.ico')
p = grafika.Aplikacija(root)
root.mainloop()
这是整个 grafika.py 文件(它很长......)

当我从 grafika.py 文件中的主文件运行代码时,它工作正常,没有错误或任何东西......
