Python Tkinter csv读取文件到Entry

Question

我正在尝试打开一个 csv 文件，循环遍历并在 Tkinter 输入框中显示 csv 文件中的内容，以便我能够手动编辑然后写入该文件

我尝试将标签更改为条目，但是当我执行任何操作时，条目中均未显示任何内容

def panel_admin():

    admingui.destroy()
    adminpanel = Toplevel()

    with open("Staff Bookings.csv", newline = "") as file:
        reader = csv.reader(file)


        r = 0
        for col in reader:
            c = 0
            for row in col:

                Label(adminpanel, width = 10, height = 2, \
                                   text = row, relief = RIDGE).grid(row = r, column = c)
                c += 1
            r += 1

您不能像设置标签一样设置条目字段的文本。您需要使用条目小部件的插入方法，如下所示

def panel_admin():

    admingui.destroy()
    adminpanel = Toplevel()

    with open("Staff Bookings.csv", newline = "") as file:
        reader = csv.reader(file)


        r = 0
        for col in reader:
            c = 0
            for row in col:

                curEntry = Entry(adminpanel, width = 10, relief = RIDGE)
                curEntry.grid(row = r, column = c)
                curEntry.insert(0, row)
                c += 1
            r += 1

请注意，如果您想写出已编辑的输入字段，您可能应该将 curEntry 存储在列表或字典中，以便稍后访问。例如，您可以使用类似下面的代码将行、列号保留为字典键，并将 Entry 小部件保留为值

fields[(r,c)] = curEntry
