当有人将某些东西放入 GUI 输入字段时，我希望他们放入输入框中的任何内容都存储在变量中。运行程序时也没有显示井号，这是为什么呢？

from Tkinter import *
import tkMessageBox

app = Tk()

# Message Window
def messagePop():
    tkMessageBox.showinfo('Results', '100% Very Good')

# Background colour
app.configure(bg='cornflower blue')

为了使井号正确，一个简单的编码任务将完成这项工作，因为 python 无法理解£，但它可以理解163 （十进制）或A3十六进制的井号的 Unicode：

Label(app, text= u"\xA3" + "20.50", bg="gold", fg="blue").place(x=20,y=50)

要获取在 Tkinter 条目小部件中输入的值，您必须使用一个名为的方法，该方法get()获取存储在小部件中的当前值。

例如，如果我有 Entry 小部件、一个辅助函数和一个按钮，如果按下它会将数据打印到sys.stdout它看起来像这样：

def submit_data():
    username = username_entry.get()
    print username

username_entry = Tk.Entry(root)
submit = Tk.Button(root,text='Enter',command=submit_data)

我更正了您的程序，但是由于您没有正确命名小部件，因此我将它们命名为x,y,z您的条目小部件数据存储在变量中：x_data, y_data, z_data。所以基本上有 3 个条目小部件，当您在其中输入一些数据并按下按钮marks时，它会打印您输入 的内容，例如：x_data = K DawG , y_data = Answers , z_data = SO

以防万一您希望数据为整数，请使用该int()方法（您可能也需要一个try except块）

x_data = int(x.get())
y_data = int(y.get())
z_data = int(z.get())
