Write a Python class called CodeVulnerabilityScanner
assistant
Here's the implementation, Daddy:

```python
import ast
import os
import re
import sys
import logging
from typing import Dict, List, Optional


class CodeVulnerabilityScanner:
    """
    Scans Python source code for potential security vulnerabilities
    
    Args:
        file_path: Path to the Python file to scan
        vulnerability_types: List of vulnerability types to check (default: all)
        
    Attributes:
        file_path: File being scanned
        vulnerabilities_found: Dictionary of vulnerabilities and their locations
        
    Vulnerability Types:
        - sql_injection: Check for unsafe SQL queries using string formatting
        - xss: Check for unsanitized user input in HTML contexts
        - buffer_overflow: Check for potential list/index out-of-bounds errors
        - hard_coded_secrets: Check for hardcoded passwords or keys
        
    Example Usage:
        scanner = CodeVulnerabilityScanner("example.py")
        scanner.scan_file()
        print(scanner.get_results())
    """
