Fixing Password & Array Validator

[bandirevanth]

Issues in the code (of password_validator.py):

• Missing return False: Many methods lacked a return False, causing them to return None and break logical checks.
• Limited special character regex: [_@$] was too restrictive; it excluded many common special characters.
• Non-PEP8 naming: Method names used CamelCase instead of Pythonic snake_case.
• Unsafe default argument: list_values used a mutable default (list), which is unsafe.
• Assumed read_file existence: Used self.read_file() without confirming its presence in BaseValidator.

I have fixed the code, guide me on the next steps.

Issues in the code (of array_validator.py):

Fix	Description
snake_case method names	Replaced isArray → is_array, etc., to follow PEP8 naming conventions
min, max renamed	Avoided shadowing Python built-in functions min() and max()
Return guards for non-list inputs	Ensured each method checks isinstance(value, list) before proceeding
Handled None in max_length	Allowed optional upper bounds in is_array_length
Handled unhashable elements in set()	Added fallback logic for unhashable types (like dicts/lists) in uniqueness check
