AttributeError: 'str' object has no attribute 'tk' when click button

Question

这是我的代码：


window = tk.Tk()


version = tk.Label(text="hi",
                   fg="orange",
                   bg="black",
                   width=20,
                   height=10,
                   )
version.pack()
enter = tk.Button(text="START",fg="blue",width=20,height=7)
enter.pack()

def click(event):
    version.forget()
    enter.forget()
    name = tk.Label("name")
    entry = tk.Entry()
    name.pack()
    entry.pack()


enter.bind("<Button-1>", click)



window.mainloop()

如您所见，我想在单击“开始”按钮后显示一个标签和一个条目。

但是，当我点击按钮时，它 returns 这个错误：

Exception in Tkinter callback
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/tkinter/__init__.py", line 1892, in __call__
    return self.func(*args)
  File "/Users/name/Desktop/project/gui/main.py", line 19, in click
    name = tk.Label("name")
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/tkinter/__init__.py", line 3148, in __init__
    Widget.__init__(self, master, 'label', cnf, kw)

    self.tk = master.tk
AttributeError: 'str' object has no attribute 'tk'

我不知道这里发生了什么。

Answer 1

根据错误陈述，问题的根源是这一行：

File "/Users/name/Desktop/project/gui/main.py", line 19, in click
    name = tk.Label("name")

Label 的第一个预期参数是“master”或父级 window。
