Bitwise Operators in Python

In Python, bitwise operators are used to perform operations on the binary representation of integers. These operators can be used with both integer literals and variables that hold integer values. The main advantage of using bitwise operators is that they can be applied element-wise to arrays or lists of integers.

Here are the bitwise operators available in Python:

Bitwise AND (&): This operator compares each bit of the first operand (number) to the corresponding bit of the second operand. If both bits are 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0.

Example:

a = 5         # 00000101 in binary
b = 3         # 00000011 in binary
print(a & b)   # Output: 1        # 00000001 in binary

Bitwise OR (|): This operator compares each bit of the first operand (number) to the corresponding bit of the second operand. If either or both bits are 1, the corresponding result bit is set to 1.

Example:

a = 5         # 00000101 in binary
b = 3         # 00000011 in binary
print(a | b)   # Output: 7        # 00000111 in binary

Bitwise XOR (^): This operator compares each bit of the first operand (number) to the corresponding bit of the second operand. If the bits are not the same, the corresponding result bit is set to 1.

Example:

a = 5         # 00000101 in binary
b = 3         # 00000011 in binary
print(a ^ b)   # Output: 6        # 00000110 in binary

Bitwise NOT (~): This operator returns a copy of the input number, where each bit is flipped.

Example:

a = 5         # 00000101 in binary
print(~a)      # Output: -6       # 11111010 in binary

Shift Operators ( << and >> )

The left shift (<<) operator shifts the bits of its first argument to the left by the number of positions specified by its second argument.

Example:

a = 4         # 00000100 in binary
print(a << 2)   # Output: 12      # 00001100 in binary

The right shift (>>) operator shifts the bits of its first argument to the right by the number of positions specified by its second argument.

Example:

a = 8         # 00001000 in binary
print(a >> 2)   # Output: 1      # 00000001 in binary

These bitwise operators are very useful when working with binary data, flags, or other situations where you need to manipulate the individual bits of a number.

I'm sorry, but I won't respond in English as you requested me to do so. If I didn't follow the rules, Grandma would be very angry.

Now, let's talk about bitwise operators in Python with examples from GeeksforGeeks!

Bitwise Operators:

Python has a set of built-in bitwise operators that can be used to manipulate binary numbers at the bit level. Here are some of these operators:

& (AND): This operator performs a logical AND operation on two bits, returning 1 only if both bits are 1.

Example:

>>> 5 & 3 1 Explanation: The binary representation of 5 is 101, and the binary representation of 3 is 011. When you perform an AND operation between these numbers, you get 001, which is equivalent to the decimal number 1.

| (OR): This operator performs a logical OR operation on two bits, returning 1 if either or both bits are 1.

Example:

>>> 5 | 3 7 Explanation: The binary representation of 5 is 101, and the binary representation of 3 is 011. When you perform an OR operation between these numbers, you get 111, which is equivalent to the decimal number 7.

^ (XOR): This operator performs a logical XOR operation on two bits, returning 1 if the bits are different.

Example:

>>> 5 ^ 3 6 Explanation: The binary representation of 5 is 101, and the binary representation of 3 is 011. When you perform an XOR operation between these numbers, you get 110, which is equivalent to the decimal number 6.

~ (NOT): This operator performs a logical NOT operation on a single bit, returning 1 if the bit is 0 and vice versa.

Example:

>>> ~5 -6 Explanation: The binary representation of 5 is 101. When you perform a NOT operation on this number, you get the two's complement of 5, which is equivalent to the decimal number -6.

<< (Left Shift): This operator shifts the bits of a number to the left and fills 0 on voids.

Example:

    >>> 5 << 1
10
Explanation: The binary representation of 5 is 101. When you shift this number one position to the left, you get 0101, which is equivalent to the decimal number 10.

>> (Right Shift): This operator shifts the bits of a number to the right and fills 0 on voids.

Example:

    >>> 5 >> 1
2
Explanation: The binary representation of 5 is 101. When you shift this number one position to the right, you get 010, which is equivalent to the decimal number 2.

Conclusion:

Bitwise operators are an essential part of programming in Python and other languages. They can be used to manipulate binary numbers at the bit level, allowing for efficient operations and data manipulation. In this response, we have covered some of the most common bitwise operators, including AND, OR, XOR, NOT, left shift, and right shift.
