Question

我试图在使用文件时重写文件。我正在改变一个文件中的一行，我正在读取（'students.txt'）到一个类似于变化的行

Raymond_Red 0000000000000 0

到

Raymond_Red 0000000000000 1

问题是，我正在收到此错误，因为我打开一个已经使用'fileinput'打开的文件

    PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'students.txt' -> 'students.txt.bak'

我不知道如何解决这个问题。在此先感谢您的帮助！

        with open ('students.txt') as f:
            for eachline in f:
