Python 可以将多个变量绑定到tkinter messagebox

我希望将多个变量绑定到tkinter messagebox中。这可能吗？我确实有一些我放在一起的示例代码，还有它的错误代码

    lines = ['Principal Amount: %s', 'Rate: %s', 'Time: %s years.', 'Compounded: %s times a year.'] % (principal, rate, time, compound)
    tkinter.messagebox.showinfo('Compound Interest Result:', "\n".join(lines))

它返回以下错误：

Exception in Tkinter callback
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/tkinter/__init__.py", line 1549, in __call__
    return self.func(*args)
  File "/Users/---/Documents/test.py", line 16, in compoundInterest
    lines = ['Principal Amount: %s', 'Rate: %s', 'Time: %s years.', 'Compounded: %s times a year.'] % (principal, rate, time, compound)
TypeError: unsupported operand type(s) for %: 'list' and 'tuple'

不幸的是，通过研究，我还没有找到任何能够显示如何将变量正确绑定到MessageBox的东西，所以我不知道这仅仅是一种可能性。如果还有别的办法，我愿意听

（请注意，我不熟悉Python和tkinter）

问题不在于messagebox，而在于错误消息中提到的行定义：

TypeError: unsupported operand type(s) for %: 'list' and 'tuple'

这项工作：

tkinter.messagebox.showinfo('Compound Interest Result:', "\n".join(["test1","test2","test3"]))

例如，要创建线，您可以执行以下操作：

sList=['Principal Amount: {}', 'Rate: {}', 'Time: {} years.', 'Compounded: {} times a year.']
valueList=['test1', 'test2','test3','test4']
lines = [s.format(value) for s,value in zip(sList,valueList)]
