intf provides a simple base class for integers with specified default formatting. Define your own subclasses derived from BaseIntF and specify desired formatting right with the class name. Decimal, binary, octal and hexadecimal formats are supported. See BaseIntF for more details.

Example:

from intf import BaseIntF

class int_04X(BaseIntF):
    pass

x = int_04X(123)
print '{}'.format(x)  # prints 0x007B

class int_06o(BaseIntF):
    pass

y = int_06o(123)
print '{}'.format(y)  # prints 0o000173

class int_08b(BaseIntF):
    pass

z = int_08b(123)
print '{}'.format(z)  # prints 0b01111011

print '{:02x}'.format(z)  # still prints 7b
