for循環將東西插入tkinter窗口

Question

我有Tkinter程序必須添加大量的數據到窗口，所以我試圖寫一個for循環來照顧它，但由於我必須使用字符串變量用於Tkinter在對象上運行.insert（）的對象的名稱。我沒有解釋得很好這裏是方法

def fillWindow(self): 
     global fileDirectory 
     location = os.path.join(fileDirectory, family + '.txt') 
     file = open(location, 'r') 

     ordersDict = {} 
     for line in file: 
      (key, value) = line.split(':', 1) 
      ordersDict[key] = value 

     for key in ordersDict: 
      ordersDict[key] = ordersDict[key][:-2] 

     for item in ordersDict: 
      if item[0] == '#': 
       if item[1] == 'o': 
        name = 'ordered%s' %item[2:] 

right here is the problem line because I have the variable that matches the name of the entry object already created but 'name' is actually a string variable so it gives me the error "AttributeError: 'str' object has no attribute 'insert'"

    name.insert(0,ordersDict[item]) 

這裏是整個類。它製作了一個Tkinter窗口，並用一種​​運輸屏幕填充它，所以所有條目都是需要多少訂單的。我也很新，所以我知道我做很多很長的事情。

class EditShippingWindow(Tkinter.Toplevel): 

def __init__(self, student): 

    Tkinter.Toplevel.__init__(self) 
    self.title('Orders') 

    family = student 

    ## Window Filling 

    ageGroupLabel = Tkinter.Label(self,text='Age Group') 
    ageGroupLabel.grid(row=0,column=0) 

    itemColumnLabel = Tkinter.Label(self,text='Item') 
    itemColumnLabel.grid(row=0, column=1) 

    costColumnLabel = Tkinter.Label(self,text='Cost') 
    costColumnLabel.grid(row=0, column=2) 

    orderedColumnLabel = Tkinter.Label(self,text='Ordered') 
    orderedColumnLabel.grid(row=0, column=3) 

    paidColumnLabel = Tkinter.Label(self,text='Paid') 
    paidColumnLabel.grid(row=0, column=4) 

    receivedColumnLabel = Tkinter.Label(self,text='Received') 
    receivedColumnLabel.grid(row=0, column=5) 



    #Item Filling 

    column1list = ['T-Shirt (2T):$9.00', 'T-Shirt (3T):$9.00', 'T-Shirt (4T):$9.00', 
        'Praise Music CD:$10.00', ':', 'Vest L(Size 6):$10.00', 'Vest XL(Size 8):$10.00',

        '4th & 5th Gr. Book 1 (KJ/NIV/NKJ):$8.75', '4th & 5th Gr. Book 2 (KJ/NIV/NKJ):$8.75', 
        'Memory CD 3rd & 4th Gr. Book (1/2):$10.00', 'Drawstring Backpack:$5.50'] 
    column1num = 1 
    for item in column1list: 
     num = str(column1num) 

     (title, price) = item.split(':') 

     objectName1 = 'column1row' + num 
     objectName1 = Tkinter.Label(self,text=title) 
     objectName1.grid(row=column1num, column=1) 

     objectName2 = 'column1row' + num 
     objectName2 = Tkinter.Label(self,text=price) 
     objectName2.grid(row=column1num, column=2) 
     column1num += 1 

    #Ordered Paid Recieved Filler 

    for i in range(32): 
     if i == 11 or i == 22 or i == 0 or i == 5: 
      pass 
     else: 
      width = 10 
      # First Column 
      title1 = 'ordered' + str(i) 
      self.title1 = Tkinter.Entry(self,width=width) 
      self.title1.grid(row=i,column=3) 
      #self.title1.insert(0, title1) 

      #Second 
      title2 = 'paid' + str(i) 
      self.title2 = Tkinter.Entry(self,width=width) 
      self.title2.grid(row=i,column=4) 
      #self.title2.insert(0, title2) 

      #Third 
      title3 = 'received' + str(i) 
      self.title3 = Tkinter.Entry(self,width=width) 
      self.title3.grid(row=i,column=5) 
      #self.title3.insert(0, title3) 






    ## Methods 

    def fillWindow(self): 
     global fileDirectory 
     location = os.path.join(fileDirectory, family + '.txt') 
     file = open(location, 'r') 

     ordersDict = {} 
     for line in file:

      ordersDict[key] = value 

     for key in ordersDict: 
      ordersDict[key] = ordersDict[key][:-2] 

     for item in ordersDict: 
      if item[0] == '#': 
       if item[1] == 'o': 
        self.name = 'ordered%s' %item[2:] 

        self.name.insert(0,ordersDict[item]) 



    fillWindow(self) 

Answer 1

看起來你有一個概念錯誤：在這個方法中，變量「name」不存在直到第一個列表的最後一行。然後創建它，並指向一個普通的Python字符串 - 如果在類的其他地方使用「name」變量，則此方法中不存在該變量。

爲了您的現有代碼的一個簡單的辦法，嘗試調用該變量爲「self.name」，而不是僅僅將其命名爲創建地方，並在此方法中使用您的最後一行： self.name.insert(0,ordersDict[item])代替。

self.前綴會將您的變量變成一個實例變量，該實例變量在類的同一實例中的方法間共享。

在附註上，您甚至不需要在此方法上連續三次以上的字典，只需將您從「行」中提取的相關值插入文本變量即可。
