Why is '\x' invalid in Python?
There is a table listing all the escape codes and their meanings in the documentation.
Escape Sequence Meaning Notes\xhh Character with hex value hh (4,5)
Notes:
4. Unlike in Standard C, exactly two hex digits are required.
5. In a string literal, hexadecimal and octal escapes denote the byte with the given value; it is not necessary that the byte encodes a character in the source character set. In a Unicode literal, these escapes denote a Unicode character with the given value.
x is used to define (one byte) hexadecimal literals in strings, for example:
'\x61'will evaluate to 'a', because 61 is the hexadecimal value of 97, which represents a in ASCII
