bit_manipulation.single_bit_manipulation_operations

Provide the functionality to manipulate a single bit.

Functions

clear_bit(→ int)	Set the bit at position to 0.
flip_bit(→ int)	Flip the bit at position.
get_bit(→ int)	Get the bit at the given position
is_bit_set(→ bool)	Is the bit at position set?
set_bit(→ int)	Set the bit at position to 1.

Module Contents

bit_manipulation.single_bit_manipulation_operations.clear_bit(number: int, position: int) → int

Set the bit at position to 0.

Details: perform bitwise and for given number and X. Where X is a number with all the bits - ones and bit on given position - zero.

>>> clear_bit(0b10010, 1) # 0b10000
16
>>> clear_bit(0b0, 5) # 0b0
0

bit_manipulation.single_bit_manipulation_operations.flip_bit(number: int, position: int) → int

Flip the bit at position.

Details: perform bitwise xor for given number and X. Where X is a number with all the bits - zeroes and bit on given position - one.

>>> flip_bit(0b101, 1) # 0b111
7
>>> flip_bit(0b101, 0) # 0b100
4

bit_manipulation.single_bit_manipulation_operations.get_bit(number: int, position: int) → int

Get the bit at the given position

Details: perform bitwise and for the given number and X, Where X is a number with all the bits - zeroes and bit on given position - one. If the result is not equal to 0, then the bit on the given position is 1, else 0.

>>> get_bit(0b1010, 0)
0
>>> get_bit(0b1010, 1)
1
>>> get_bit(0b1010, 2)
0
>>> get_bit(0b1010, 3)
1

bit_manipulation.single_bit_manipulation_operations.is_bit_set(number: int, position: int) → bool

Is the bit at position set?

Details: Shift the bit at position to be the first (smallest) bit. Then check if the first bit is set by anding the shifted number with 1.

>>> is_bit_set(0b1010, 0)
False
>>> is_bit_set(0b1010, 1)
True
>>> is_bit_set(0b1010, 2)
False
>>> is_bit_set(0b1010, 3)
True
>>> is_bit_set(0b0, 17)
False

bit_manipulation.single_bit_manipulation_operations.set_bit(number: int, position: int) → int

Set the bit at position to 1.

Details: perform bitwise or for given number and X. Where X is a number with all the bits - zeroes and bit on given position - one.

>>> set_bit(0b1101, 1) # 0b1111
15
>>> set_bit(0b0, 5) # 0b100000
32
>>> set_bit(0b1111, 1) # 0b1111
15
