A bytes object is an immutable array. The items are 8-bit bytes, represented by integers in the range 0 <= x < 256. Bytes literals (like b'abc') and the built-in function bytes() can be used to construct bytes objects. Also, bytes objects can be decoded to strings via the decode() method.
Since a minimizer bra is meant to make the breasts appear smaller, the bra provides very little actual support to a woman's chest. A bra's cups are meant to provide most of the support for the chest, with maybe 10 percent of the support coming from the straps. In poorly fitted bras, and in minimizer bras, most of the support comes from the straps.
An oxygen conserver is a device that delivers oxygen only when you inhale rather than providing a continuous flow. This helps decrease the amount of O2 used and the amount of oxygen tanks needed. This also means that your oxygen tank lasts longer, which allows you more freedom to go out and about.
