[Tutor] Is there an easy way to conduct binary numbers?

[Juan Shen]

I have found there are easy functions and options to do basic octal and
hexadecimal number operation.

oct(...)
oct(number) -> string

Return the octal representation of an integer or long integer.

hex(...)
hex(number) -> string

Return the hexadecimal representation of an integer or long integer.

print '%o' %number
Print a decimal number in octal format.

print '%X' %number
Print a decimal number in hexadecimal format.

However, I can't find their binary counterpart, something like bin(...)
or print '%b'. Binary integer is extremely useful in my
electronic-related job. So...I need help. Is there any function to
transform between binary and decimal integers in python's library? If
not, what's the solution to binary?
