使用splat运算符进行Python字符串插值？

Question

I have a large (~10 elements) list of integers that I wish to interpolate into a string. This seems like an ideal use case for the splat operator, so I'd like to be able to do something like this:

"""[latex]$\begin{bmatrix}
%d & %d \\ %d & %d\end{bmatrix}
\times
\begin{bmatrix}
%d & %d \\ %d & %d
\end{bmatrix} $[/latex]""" % (*lst)
                              ^^^^ SyntaxError: invalid syntax

What is a clean, syntactically valid way to achieve this?

str.__mod__带一个元组。

'''...''' % tuple(lst)
