The PEP discusses this: """ Proposed syntaxes included things like arbitrary radix prefixes, such as 16r100 (256 in hexadecimal), and radix suffixes, similar to the 100h assembler-style suffix. The debate on whether the letter "O" could be used for octal was intense -- an uppercase "O" looks suspiciously similar to a zero in some fonts. Suggestions were made to use a "c" (the second letter of "oCtal"), or even to use a "t" for "ocTal" and an "n" for "biNary" to go along with the "x" for "heXadecimal". For the string % operator, "o" was already being used to denote octal. Binary formatting is not being added to the % operator because PEP 3101 (Advanced String Formatting) already supports binary, % formatting will be deprecated in the future. At the end of the day, since uppercase "O" can look like a zero and uppercase "B" can look like an 8, it was decided that these prefixes should be lowercase only, but, like 'r' for raw string, that can be a preference or style-guide issue. """ Personally I would have preferred the "t". -- https://mail.python.org/mailman/listinfo/python-list
