Question

是python的新手，只是想在GUI中创建一个简单的Minecraft服务器属性文件创建者，我发现它没有正确写入文件并给我这个错误 - “

Exception in Tkinter callback
Traceback (most recent call last):
  File "D:\Python33\lib\tkinter\__init__.py", line 1475, in __call__
    return self.func(*args)
  File "D:\Python33\Projects\Server\GUI.py", line 26, in top
    f.write(line1)
ValueError: I/O operation on closed file.

欢迎任何帮助！

当你收到错误时，这意味着你正试图玩一个没有意义的关闭文件。所以在做任何事之前确保文件是打开的......

这可能意味着您的一行代码在最终f.write()执行之前关闭了该文件。我可以提供的最佳建议是在f = open('file','w')

之前致电f.write()

Python：Server Creator - 不写入文件
