Button实例没有__call__方法

-4

我想在python中创建应用程序，所以我刚刚开始，我想单击按钮并显示图形！Button实例没有__call__方法

但它不允许我这样做。

代码片段：

from Tkinter import * 
    import matplotlib 
    matplotlib.use('TkAgg') 
    from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg 
    from matplotlib.figure import Figure 
    import matplotlib.pyplot as plt 
def schart2(stock_sym): 
    df 
    df.astype(float) 
    labels =  ['day0','day1','day2','day3','day4','day5','day6','day7','day8','day9','day10','day11','day12','day13','day14','day15','day16','day17','day18','day19','day20','day21','day22','day23','day24','day25','day26','day27','day28','day29','day30'] 

    df.columns=labels 
    plt.subplots_adjust(left=0.1, bottom=0.15, right=0.99, top=0.95) 
    ax=plt.imshow(df, cmap=plt.cm.get_cmap("RdPu"), interpolation="nearest",aspect="auto") 
    plt.xticks(range(len(labels)), labels, rotation=90, va="top", ha="center") 

    plt.colorbar() 
    plt.title("Return rate Retention") 
    plt.xlabel("Retention Days") 
    plt.ylabel("Total Days") 
    fig=ax.get_figure() 
    plt.show() 

class StockChart(Frame): 
    def __init__(self, stock_sym=''): 
     Frame.__init__(self, parent=None) 
     self.pack(expand=YES, fill=BOTH) 
     self.create_widgets(stock_sym) 
     self.makeWidgets(stock_sym) 

    def create_widgets(self, stock_sym): 
     self.makeWidgets = tk.Button(self) 
     self.makeWidgets["text"] = "Hello World\n(click me)" 
     self.makeWidgets["command"] = self.makeWidgets 
     self.makeWidgets.pack(side="top") 

     self.quit = tk.Button(self, text="QUIT", fg="red", 
           command=root.destroy) 
     self.quit.pack(side="bottom") 

    def makeWidgets(self, stock_sym): 
     #self.f = graphData(stock_sym,12,26) 
     self.f = schart2(stock_sym) 
     self.canvas = FigureCanvasTkAgg(self.f) 
     self.canvas.get_tk_widget().pack(side=Tk.TOP, fill=Tk.BOTH, expand=1) 
     self.canvas.show() 



if __name__ == '__main__': 
    StockChart('ACAD').mainloop()

而且错误是：

self.makeWidgets(stock_sym) 
AttributeError: Button instance has no __call__ method

我这样做完全错误的或者是有一个简单的方法来解决这一问题？任何帮助将不胜感激。

似乎有像15级或20的错误和错误代码你发布了...你是写这个还是它是来自各种来源的剪切和粘贴的组合？它有没有跑，在早期阶段？你可以发布一些更简单的东西，在你修改一段代码后产生了一个错误吗？ –

你的变量

self.makeWidgets = tk.Button(self)

具有相同的名称类方法

def makeWidgets(self, stock_sym):

首先尝试改变这种
