Meaning of 0x and \x in python hex strings?

Question

I\'m doing some binary operations which are often shown as hex-es. I have seen both the 0x and \\xas prefixes.

In which case is which used

Answer 1

0x is used for literal numbers. "\x" is used inside strings to represent a character

>>> 0x41
65
>>> "\x41"
'A'

>>> "\x01" # a non printable character
'\x01'

Answer 2

0x follows number, means HEX number

\x follows number, means HEX ascii characters
