How do I manipulate bits in Python?

Question

In C I could, for example, zero out bit #10 in a 32 bit unsigned value like so:

unsigned long value = 0xdeadbeef;
value &= ~(1<<10);

Answer 1

Some common bit operations that might serve as example:

def get_bit(value, n):
    return ((value >> n & 1) != 0)

def set_bit(value, n):
    return value | (1 << n)

def clear_bit(value, n):
    return value & ~(1 << n)

Usage e.g.

>>> get_bit(5, 2)
True
>>> get_bit(5, 1)
False
>>> set_bit(5, 1)
7
>>> clear_bit(5, 2)
1 
>>> clear_bit(7, 2)
