A stupid simple Python utility to quickly print out the alignment of an integer provided on the command line.

alignof.py

import sys

def check_alignment(val):
    alignments = {
        '2-byte': val & 0x1 == 0,
        '4-byte': val & 0x3 == 0,
        '8-byte': val & 0x7 == 0,
        '16-byte': val & 0xF == 0,
        '32-byte': val & 0x1F == 0,
        '64-byte': val & 0x3F == 0,
        '128-byte': val & 0x7F == 0,
        '256-byte': val & 0xFF == 0,
    }
    
    # Check all alignments and store those that are true
    satisfied_alignments = [alignment for alignment, is_aligned in alignments.items() if is_aligned]
    
    return satisfied_alignments

def number_aliases(numStr):
    val = int(numStr, 16)
    return {
            'binary:': bin(val),
            'decimal:': val,
            'hex:': numStr,
    }

# Example usage:
if len(sys.argv) > 1:
    argument = sys.argv[1]
    print("Integer aliases:")
    for x in number_aliases(argument).items():
        print(" ", x[0], str(x[1]))

    print()

    results = check_alignment(int(argument, 16))
    if len(results) == 0:
        print("This val: {} is only 1-byte aligned (NOT ALIGNED)".format(argument))
    else:
        print("The val: {} is aligned".format(argument))
        for x in results:
            print(" ", x)
else:
    print("Provide a single integer value please.")
