Adding several numbers together is a common intermediate step in many computations, so sum () is a pretty handy tool for a Python programmer. Web6.1 Sum-of-Products A sum-of-products (SOP) expression is a boolean expression in a specific format. The term sum-of-p roducts comes from the expression's form: a sum (OR) of one or more products (AND). As a digital circuit, an SOP expression takes the output of one or more AND gates and OR's them together to create the final output.
