每個用戶的新列表條目

Question

我忙於做一個學校任務，我已經停留在這段代碼，任何援助將不勝感激。 請參見下面的代碼：

from tkinter import * 

student_list = [['Tom','Information Systems'],['John','Computers'],['Johannes','Information Systems']] 

class App(Frame): 
    def __init__(self,parent=None,**kw):  
     Frame.__init__(self,master=parent,**kw) 
     self.searchValue = StringVar() 
    self.searchBox = Entry(self,textvariable=self.searchValue) 
    self.searchBox.pack() 
    self.resultList = Listbox(self) 
    self.resultList.pack() 

    self.searchBox.bind('<Return>',self.update) 

def update(self,e): 
    print("*") 
    self.resultList.delete(0,END) 
    searchkey = self.searchValue.get() 
    for student in student_list: 
     if searchkey == student[0]: 
      self.resultList.insert(END,str(student)) 
     elif searchkey == student[1]: 
      self.resultList.insert(END,str(student)) 

if __name__ == '__main__': 
    root = Tk() 
    app = App(root) 
    app.pack() 
    root.mainloop() 

是否有可能爲每個用戶創建條目或任何替代方法的新名單？

這不是很漂亮，但它的工作原理。

from tkinter import * 

student_list = [['Tom','Information Systems'],['John','Computers']] 


class App(Frame): 
    def __init__(self,parent=None,**kw): 
     Frame.__init__(self,master=parent,**kw) 
     self.searchValue = StringVar() 

     self.searchBox = Entry(self,textvariable=self.searchValue) 
     self.searchBox.pack() 
     self.resultList = Listbox(self) 
     self.resultList.pack() 
     Label(self,text="Name:").pack() 
     self.Name = Entry(self) 
     self.Name.pack() 
     Label(self,text="Course:").pack() 
     self.Course = Entry(self) 
     self.Course.pack() 
     self.btnAdd = Button(self,text="Add",command=self.add_student) 
     self.btnAdd.pack() 

     self.searchBox.bind('<Return>',self.update) 

    def add_student(self): 
     global student_list 
     print(student_list) 
     name = self.Name.get() 
     course = self.Course.get() 
     student_list.append([name,course]) 
     print(student_list) 

    def update(self,e): 
     print("*") 
     self.resultList.delete(0,END) 
     searchkey = self.searchValue.get() 
     for student in student_list: 
      if searchkey == student[0]: 
       self.resultList.insert(END,str(student)) 
      elif searchkey == student[1]: 
       self.resultList.insert(END,str(student)) 

if __name__ == '__main__': 
    root = Tk() 
    app = App(root) 
    app.pack() 
    root.mainloop() 

現在嘗試自己解決下一個問題...到目前爲止，我已經完成了兩個步驟。
