.read() returns "unicode object has no attribute read" in python with askopenfilename()

.read() returns "unicode object has no attribute read" in python with askopenfilename()

我试图在 Python 的 Tkinter 中为 scrolledText 创建一个导入函数,但是在读取文件时,出现了一个 AttributeError。代码:

def open_command():
    openfile = tkFileDialog.askopenfilename()
    if openfile != None:
        contents = openfile.read()
        textPad.delete('1.0', END)
        textPad.insert('1.0', contents)
        openfile.close()

错误:

    contents = openfile.read()
AttributeError: 'unicode' object has no attribute 'read'

我想澄清一下 'textPad' 指的是一个 'ScrolledText' 对象。 有谁知道为什么会这样?起初我以为错误可能来自编码,所以我用UTF-8编码但它仍然返回相同的错误。提前致谢!

tkFileDialog.askopenfilename() returns 文件名不是文件对象。您需要执行以下操作:

def open_command():  
    filename = tkFileDialog.askopenfilename()
    if filename is not None:
        with open(filename) as f:
           contents = f.read()
        textPad.delete('1.0', END)
        textPad.insert('1.0', contents)

[如果您正在使用 Python 2.7,请考虑使用 Python 3 或将以上内容更改为 open(filename, 'r')]
