Python 每当我尝试运行编辑函数时，该函数都会执行，但文本不会附加到文件中 def EDIT（）： 打印（“\n输入要编辑的文件”） command=input（'\n$input

您需要关闭文件以刷新缓冲区

通常最好使用上下文管理器，以便自动关闭文件

 def EDIT():
    print("\nEnter the file you want to edit")
    command = input('\n$input<<')
    try:
        f = open(command + ".txt", "a")
        f.write(input('\n$append<<'))
    except FileNotFoundError:
        print('\nSorry, there was an error while trying to create your file. The file doesn\'t exist.\n')
    finally:
        NOTEPAD()
        

def EDIT（）：
打印（“\n输入要编辑的文件”）
command=input（'\n$input请提供一个。
def EDIT():
    print("\nEnter the file you want to edit")
    command = input('\n$input<<')
    try:
        with open(command + ".txt", "a") as f:
            f.write(input('\n$append<<'))
    except FileNotFoundError:
        print('\nSorry, there was an error while trying to create your file. The file doesn\'t exist.\n')
    finally:
        NOTEPAD()
