my_string = 'hello world'

# get bytes from string
my_bytes = my_string.encode() # default is utf8. accepts: utf-8, utf16, ascii, etc
print(my_bytes)

# get hex from bytes
my_hex = my_bytes.hex() # NEW in python3.5, on python<3.4 use binascii (un)hexlify
print(my_hex)

# get string from hex
my_string_again = bytes.fromhex(my_hex).decode() # default encoding is utf8
