How can we convert a decimal number into binary using a Python program? Can you thinkof 2 methods to do it?

Sure, I can provide two methods to convert a decimal number into binary using Python.

Method 1: Using the built-in function bin()

def decimal_to_binary(n):
    return bin(n).replace("0b", "")

# Test the function
print(decimal_to_binary(10))  # Output: 1010

In this method, we use Python's built-in function bin(), which converts an integer number to a binary string prefixed with "0b". We then use the replace() function to remove this prefix.

Method 2: Using bitwise shift and bitwise AND operations

def decimal_to_binary(n):
    binary = 0
    i = 1
    while (n != 0):
        remainder = n % 2
        n = n // 2
        binary = binary + remainder * i
        i = i * 10
    return binary

# Test the function
print(decimal_to_binary(10))  # Output: 1010

In this method, we use bitwise shift (// 2) and bitwise AND (% 2) operations to get the binary equivalent of the given decimal number. We start from the least significant bit and go towards the most significant bit, multiplying the remainder by powers of 10 (to place it at the correct position in the binary number), and adding it to the binary number.
