python bitwise operations on C data types?

Is it possible to do bitwise operations on C data types in Python?

>>> from ctypes import c_uint8
>>> foo = c_uint8(4)
>>> foo << 1
Traceback (most recent call last):
  File "<stdin>",开发者_StackOverflow line 1, in <module>
TypeError: unsupported operand type(s) for <<: 'c_ubyte' and 'int'

Try foo.value << 1

or to update foo,

foo.value <<= 1

---

This works, but it isn't done at the C level:

foo.value << 1

from ctypes import c_uint8
foo = c_uint8(4)
print foo.value << 1

will print 8 as you want. To change foo, use

foo.value <<= 1
