What is hamming weight python?

The Hamming weight is the number of 1s in a binary word or string. In Python, the hamming weight can be calculated using built-in functions such as bin(), count(), and int().

The bin() function returns a binary string, the count() function counts the number of 1s in the string, and the int() function converts the string back to an integer.

Here is an example of calculating the Hamming weight of a binary number using Python:

n = 1011010
binary_string = bin(n)[2:]
hamming_weight = binary_string.count('1')
print(hamming_weight)

Output:

4

In this example, the binary representation of the number 1011010 is '1011010'. The count() function counts the number of 1s, which is 4. Therefore, the Hamming weight of the number is 4.
