This should happen automatically with the changes to The common integer system that were used to, the decimal system, uses a base of ten, meaning that it has ten different symbols. If you did not want the 0b prefix, simply drop the # and adjust the length of the field: Note for Python 2.6 or older, you cannot omit the positional argument identifier before :, so use.
