当有人将某些内容放入 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。当我运行程序时，井号也没有出现，这是为什么？

最佳答案
为了使英镑符号正确，一个简单的编码任务就可以完成这项工作，因为 python 无法理解 £，但它可以理解英镑符号的 Unicode，即 163 > (十进制) 或十六进制的 A3:
标签(app, text= u"\xA3"+ "20.50", bg="gold", fg="blue").place(x=20,y=50)
要获取在 Tkinter Entry 小部件中输入的值，您必须使用名为 get() 的方法，该方法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，按下该按钮会将数据打印到 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，但由于您没有正确命名小部件，所以我将它们命名为x,y,z，您的条目小部件数据存储在变量中:x_data、y_data、z_data 。因此，基本上有 3 个输入小部件，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
