What does a leading `x` mean in a Python string `xaa`
Question:
What is difference between 'aa' and 'xaa'? What does the x part mean? And which chapter of the Python documentation covers this topic?
Answers:
That’s unicode character escaping. See “Unicode Constructors” on PEP 100
The leading x escape sequence means the next two characters are interpreted as hex digits for the character code, so xaa equals chr(0xaa), i.e., chr(16 * 10 + 10) — a small raised lowercase 'a' character.
Escape sequences are documented in a short table here in the Python docs.
