How to fix 'AttributeError: partially initialized module 'SendEmail' has no attribute 'send_email' (most likely due to a circular import)'
How to fix 'AttributeError: partially initialized module 'SendEmail' has no attribute 'send_email' (most likely due to a circular import)'
所以我正在使用 Tkinter 创建一个 Gmail 发件人应用程序，我有一个名为 send_email 的函数，它位于 SendEmail.py 中。但是每次我 运行 代码都会给我这个错误：
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Users\User\AppData\Local\Programs\Python\Python39\lib\tkinter\__init__.py", line 1885, in __call__

所以有谁知道如何解决这个问题我被卡住了我想不通。提前致谢
您正在尝试从导入文件的文件中导入文件。这导致 circular import。相反，您应该将两个文件中需要的代码放在第三个文件中，然后将其导入两个文件中。
请参阅下面的示例
variables.py
foo = "bar"
main.py
import variables
import second
print(foo)
second.py
import variables
print(foo)
对于您的示例，您需要移动 notif、root、emailEntry、passwordEntry、receiverEntry、subjectEntry 和 bodyEntry 到另一个文件，连同他们依赖的东西。
