(Python新手)继续得到"TypeError:'int'对象不可调用"

Question

我对Python非常陌生,我正在尝试编写一个GUI程序,以便从列表中为类分配提取最频繁和最不频繁的名称.我一直在接受

TypeError:'int'对象不可调用

此代码出错,我知道它与该行有关:

word_frequencies += float[self.listMyData.Count(word)]/len[self.listMyData]  

但我不确定错误在说什么.我在这里看了类似的问题,但仍然不确定我做错了什么.任何帮助将不胜感激.

这是完整的代码:

import wx
import myLoopGUI

class MyLoopFrame(myLoopGUI.MyFrame1):
    def __init__(self, parent):
        myLoopGUI.MyFrame1.__init__(self, parent)

    def clkAddData(self,parent):
        if len(self.txtAddData.Value) != 0:
            try:
                myname = str(self.txtAddData.Value)
                self.listMyData.Append(str(myname))
            except:
                wx.MessageBox("This has to be a name!")            
        else:
            wx.MessageBox("This can't be empty")




    def clkFindMost(self, parent):
        unique_words = []
        for word in range(self.listMyData.GetCount()):
                if word not in unique_words:
                    unique_words += [word]
        word_frequencies = []
        for word in unique_words:
            word_frequencies += float[self.listMyData.Count(word)]/len[self.listMyData]  

        max_index = 0
        frequent_words =[]
        for i in range(len(unique_words)):
            if word_frequencies[i] >= word_frequencies[max_index]:
                max_index = i
                frequent_words += unique_words[max_index]
        self.txtResults.Value = frequent_words



myApp = wx.App(False)
myFrame = MyLoopFrame(None)
myFrame.Show()
myApp.MainLoop()

Count是的财产myListData.你把括号" ()"放在它后面,好像它是一个函数,但事实并非如此.它只是一个整数值.这就像这样做:

y = 5
x = y(word)

这没有意义.我不知道你想要做什么word和myListData.Count,但也许你要寻找的是self.myListData[word].Count.

如用户3666197所述,您还想更改float[...]为float(...).
