How would one load this tuple as a constant? (myfile.read(), "%.5f" % sin(x or y)) The point is that *in general*, tuple so-called "literals" (what the docs call displays) cannot be loaded as constants. If, and only if, the tuple contains nothing but immutable constants e.g. (1, 2.0, None, "spam") then a sufficiently smart compiler may be able to treat that specific tuple as a constant/literal. But that's a special case, and cannot be generalised to all tuple displays. All tuple so-called "literals" e.g. (), (1, 2), (x, y, z) etc. are fundamentally expressions that *may* have to be built at runtime. Hence the word "literal" is inappropriate. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
