This should happen automatically with the changes to Int(s, 0) will also match the new grammar definition. PEP 306 should be checked for other issues, and that PEP shouldīe updated if the procedure described therein is insufficient. The documentation will have to be changed as well: grammar.txt,Īs well as the integer literal section of the reference manual.

Integer : := decimalinteger | octinteger | hexinteger | bininteger | oldoctinteger octinteger : := '0' ( 'o' | 'O' ) octdigit + bininteger : := '0' ( 'b' | 'B' ) bindigit + oldoctinteger : := '0' octdigit + bindigit : := '0' | '1'įor Python 3.0, “oldoctinteger” will not be supported, andĪn exception will be raised if a literal has a leading “0” andįor both versions, this will require changes to PyLong_FromString

Some Python users have a strong desire for binary support in.

Language itself, which is not the meaning that most humans would To inadvertently create an integer object with the wrong value,īecause ‘013’ means ‘decimal 11’, not ‘decimal 13’, to the Python To people unfamiliar with C-like languages.

The default octal representation of integers is silently confusing.

This PEP was motivated by two different issues:

provision will be made for binary numbers in.

binary literals are now supported via a.
