Mismatch occurs within the "Notes" section,row 1.Here is the link:https://docs.python.org/3/library/stdtypes.html#old-string-formatting The course of coding shows below: >>>'%#07o' % 1223 Result value is '0o02307',which is not in line with the description. Description is "The alternate form causes a leading zero ('0') to be inserted between left-hand padding and the formatting of the number if the leading character of the result is not already a zero." |

Looks like a leftover relic from Python 2. In Python 3, the prefix is “0o”, not just “0”. This matches to change in Python 2 to 3 octal literal syntax. And there is no special handling of zero in 3: >>> "%#o" % 0 '0o0' |

The documentation for %x etc also had the same problem, and it applies to Python 2 for %x. Here is a patch for Python 3. The behaviour is already tested, but there were some quirks due to porting from Py 2 tests, and duplicate tests which I removed. |
