进行此类导入的正确方法是什么

Question

这是我当前的文件夹结构

└── Main folder/
    ├── subfolder/
    │   ├── subfolder_function.py
    │   └── subfolder_function2.py
    └── main.py

screenshot

这些是每个文件的内容

subfolder_function2.py

def subfolder_function2():
    print("Hey I'm subfolder_function2.py")

subfolder_function.py

from subfolder_function2 import subfolder_function2

def my_function_from_subfolderfunc2():
    subfolder_function2()

main.py

from subfolder.subfolder_function import my_function_from_subfolderfunc2

if __name__ == '__main__':
    print(my_function_from_subfolderfunc2()))

为什么我总是收到此错误：

Traceback (most recent call last):
  File "C:\R24\Main folder\main.py", line 1, in <module>
    from subfolder.subfolder_function import my_function_from_subfolderfunc2
  File "C:\R24\Main folder\subfolder_function.py", line 1, in <module>
    from subfolder_function2 import subfolder_function2
ModuleNotFoundError: No module named 'subfolder_function2'

从 subfolder_function2.py 访问函数的正确方法是什么？
