8. 'bytes ', String Conversion into word throttling. The first input parameter is the string to be converted, and the second parameter is encoded into bytes.

Class bytes (object) | bytes (iterable_of_ints)-> bytes
# Bytes ([1, 2, 3, 4]) bytes must be in range (0,256) | bytes (string, encoding [, errors])-> bytes
# Bytes ('your mom Hi ', encoding = 'utf-8') | 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 | Methods defined here: | _ add _ (self, value,/) | Return self + v Alue. | _ contains _ (self, key,/) | Return key in self. | _ eq _ (self, value,/) | Return self = value. | _ ge _ (self, value,/) | Return self> = value. | _ getattribute _ (self, name,/) | Return getattr (self, name ). | _ getitem _ (self, key,/) | Return self [key]. | _ getnewargs __(...) | _ gt _ (self, value,/) | Return self> value. | _ hash _ (self,/) | Return hash (self ). | _ iter __ (Self,/) | Implement iter (self ). | _ le _ (self, value,/) | Return self <= value. | _ len _ (self,/) | Return len (self ). | _ lt _ (self, value,/) | Return self <value. | _ mod _ (self, value,/) | Return self % value. | _ mul _ (self, value,/) | Return self * value. n | _ ne _ (self, value,/) | Return self!

ASCII words start with uppercase | characters, all remaining cased characters have lowercase. | translate (self, table,/, delete = B '') | Return a copy with each character mapped by the given translation table. | table | Translation table, which must be a bytes object of length 256. | All characters occurring in the optional argument delete are removed. | The remaining characters are mapped through the given translation table. | upper (...) | B. upper ()-> copy of B | Return a copy of B with all ASCII characters converted to uppercase. | zfill (...) | B. zfill (width)-> copy of B | Pad a numeric string B with zeros on the left, to fill a field | of the specified width. B is never truncated. | attributes | Static methods defined here: | maketrans (frm, to,/) | Return a translation table useable for the bytes or bytearray translate method. | The returned table will be one where each byte in frm is mapped to the byte at | the same position in. | The bytes objects frm and to must be of the same length.
