The following table summarizes the operator precedence in Python, from highest
precedence (most binding) to lowest precedence (least binding). Operators in
the same box have the same precedence. Unless the syntax is explicitly given,
operators are binary. Operators in the same box group left to right (except for
exponentiation, which groups from right to left).
