Note how the exponentiation operator is still higher in priority than the binding addition operator that
delimits the real and imaginary components of a complex number. Regarding the last example above,
we grouped the components of the complex number together to obtain the desired result.
5.5.4. *Bit Operators (Integer-Only)
Python integers may be manipulated bitwise and the standard bit operations are supported: inversion,
bitwise AND, OR, and exclusive OR (aka XOR), and left and right shifting. Here are some facts regarding
the bit operators:
● Negative numbers are treated as their 2's complement value.
● Left and right shifts of N bits are equivalent to multiplication and division by (2 ** N) without
overflow checking.
● For longs, the bit operators use a "modified" form of 2's complement, acting as if the sign bit
were extended infinitely to the left.
The bit inversion operator ( ~ ) has the same precedence as the arithmetic unary operators, the highest
of all bit operators. The bit shift operators ( > ) come next, having a precedence one level
below that of the standard plus and minus operators, and finally we have the bitwise AND, XOR, and OR
operators (&, ^, | ), respectively. All of the bitwise operators are presented in the order of descending
priority in Table 5.4.
