0b101010 0c660 0xffe I.e. the first letter from "bin", the second from "oct", the third from "hex". Also "0c" resembles "oc" from "oct".

-1 on "c" It's too visually close to "0" in some fonts.

+1 on "t"

"t" does not appear in 'binary' or 'hexadecimal' "x" does not appear in 'binary' or 'octal' "b" does not appear in 'octal' or 'hexadecimal'

And finally "c" means "character" in %s or PEP3101, and "t" is not yet defined as a type specifier.

So just to couch it all in terms of a proposal:

In 2.6 and 3.0, we add 0t1234 as a valid octal number
In 2.6, we issue a deprecation warning for a leading literal 0 which is followed immediately by another digit.
In 3.0, that becomes an exception
If people really are still using octal that much, we should also consider adding it in to PEP3101.
