Help on class bytes in module builtins:
class bytes(object)
| bytes(iterable_of_ints) -> bytes
| bytes(string, encoding[, errors]) -> bytes
| bytes(bytes_or_buffer) -> immutable copy of bytes_or_buffer
| bytes(int) -> bytes object of size given by the parameter initialized with null bytes
| bytes() -> empty bytes object
|
| Construct an immutable array of bytes from:
| - an iterable yielding integers in range(256)
| - a text string encoded using the specified encoding
| - any object implementing the buffer API.
| - an integer

| table
| Translation table, which must be a bytes object of length 256.

|
| maketrans(frm, to, /)
| Return a translation table useable for the bytes or bytearray translate method.
