在监视目录时更改 Python 中的文件名编码

问题描述

我使用看门狗库来跟踪我的 Python 脚本中的文件更改事件。我使用 filename.encode("cp1252").decode("utf-8") 解码我的文件名，稍后重命名。例如 "C:\PACIENTI\ElÄ«za.txt".encode("cp1252").decode("utf-8") === "C:\PACIENTI\Elīza.txt" 我最后使用的是 def whatisthis(filename): 并且如果 isinstance 来检查我从“os.listdir("C:\PACIENTI\")”收集的文件名是否是已编码或未编码，仅在需要时调用重命名函数。

主要问题是编码正确地发生在看门狗处理程序类之外。第二个问题是“whatisthis(filename):”根本没有发生。

    DIRECTORY_TO_WATCH = "C:\\PACIENTI"

            event_handler,self.DIRECTORY_TO_WATCH,recursive=True)

        try:
            while True:
                time.sleep(5)
        except:
            self.observer.stop()
            # print "Error"

        self.observer.join()
