What does a leading `x` mean in a Python string `xaa`
What does a leading `x` mean in a Python string `xaa`
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.
Thats unicode character escaping. See Unicode Constructors on PEP 100
