\x escape denotes a character encoded by the single-byte hex value given by the next two characters. For example, the capital letter '
N' has the value 78, which is
4e in hex. Hence,
>>> '\x4e' 'N'
The backspace "character'' is encoded as hex
08, which is why
\b is equivalent to
>>> 'hello\b\b\b\b\bgoodbye' 'hello\x08\x08\x08\x08\x08goodbye'
Sending this string to the
print() function outputs the string formed by the sequence of characters in this string literal:
>>> print('hello\b\b\b\b\bgoodbye') goodbye
