问题描述

我不断收到此错误.有人知道如何解决这个问题吗?

I keep getting this error. Does anyone know how to solve this?

推荐答案

在您的代码中，phrase_display()需要一个x参数.

In your code, phrase_display() requires an x parameter.

   def phrase_display(x):
       textbox1.delete("1.0", "end")
       textbox1.insert(tk.END, str(x))
       textbox1.pack()

但是在Combined_funcs()

But in combined_funcs()

# to have more than 2 commands in a button    
def combine_funcs(*funcs):
    def combined_func(*args, **kwargs):
        for f in funcs:
            f(*args, **kwargs)
    return combined_func

您正在同时调用datamine()和phrase_display().虽然datamine()不需要参数，但是phrase_display()却需要；但是您没有在调用中提供x参数. f(*args, **kwargs).

You are calling both datamine() and phrase_display(). While datamine() doesn't need a parameter, phrase_display() does; but you aren't supplying the x parameter in the call. f(*args, **kwargs).

我认为[1]或[2]是您可以看的东西.

I think [1] or [2] are something you can look at.
