Fortunately, we don't have to come up with syntax that works with other
languages, only Python.

But it's not a statement, its an expression.

How about "antidisestablishmentarianism"? That's unlikely to be used in
many programs, so we could make it a keyword.
I jest, of course. But I don't think "with" reads well, and given
doesn't really work for me either *as prose*.
In my experience mathematicians put the given *before* the statement:
Given a, b, c three sides of a triangle, then
Area = sqrt(s*(s-a)*(s-b)*(s-c))
where s = (a + b + c)/2 is the semi-perimeter of the triangle.
For the record, that is almost exactly what I wrote for a student
earlier today, and its not just me, it is very similar to the wording
used on both Wolfram Mathworld and Wikipedia's pages on Heron's Formula.
Putting "given" after the expression is backwards.
