def hello():
    while True:
        global opened, filepath
        command = input("save or open: ")
        opened = False
        filepath = "Empty"
    
        if command == "save":
            if opened:
                print(f"yes you opened a file {filepath}")
            else:
                print(f"no you didn't open a file {filepath} {opened}")
        elif command == "open":
            filepath = "/home/pi/Desktop/testing.txt"
            opened = True
            print(f"opened {filepath} {opened}")
        else:
            print("typo")

hello()

我想更改打开的文件路径变量，正如我试图演示的那样，但我未能这样做，我需要在需要时更改文件路径，但事实并非如此。它只是不注册和更改这两个变量并分别打印出 Empty 和 Fasle 。顺便说一句，这是我的输出：

save or open: open
opened /home/pi/Desktop/testing True
save or open: save
no you didn't open a file Empty False
