hello,
Why gives "k = 09" a syntax error ?
You have gotten the 2.x answer. In 3.0, 0b,0o,0x prefixes are valid and
required for binary, octal, and hexadecimal literals. 0digits is invalid.
except 00, 000, etc.
Is it documented? :-)
Very clearly.
Integer literals
Integer literals are described by the following lexical definitions:
integer ::= decimalinteger | octinteger | hexinteger | bininteger
decimalinteger ::= nonzerodigit digit* | "0"+
nonzerodigit ::= "1"..."9"
digit ::= "0"..."9"
octinteger ::= "0" ("o" | "O") octdigit+
hexinteger ::= "0" ("x" | "X") hexdigit+
bininteger ::= "0" ("b" | "B") bindigit+
octdigit ::= "0"..."7"
hexdigit ::= digit | "a"..."f" | "A"..."F"
bindigit ::= "0" | "1"
