Question

我正在忙着完成一项学校作业，而且我已经陷入了这段代码，任何帮助都会非常感激。请参阅以下代码：

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()

是否可以为每个用户条目或任何替代方法创建新列表？

这不太好但是有效。

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()

现在尝试自己解决下一个问题......到目前为止，我已经为你完成了两个步骤。
