• Heuristic parser for messy input (labels, mixed delimiters, extra text)
• Parse-time CVV length validation (3 or 4 digits)
• Luhn validation and expiry validation helpers
• CVV validation with card-type awareness
• Card type detection across 20 major networks
• Formatting and masking helpers
• CLI for quick parsing and validation

card = CCParser("4111111111111111|12|2030|123")
print(card.get_number())           # 4111111111111111
print(card.get_formatted_number()) # 4111 1111 1111 1111
print(card.get_expiry())           # 12/30
print(card.get_cvv())              # 123
print(card.is_valid())             # True
print(card.get_card_type())        # Visa
print(card.get_masked_number())    # **** **** **** 1111
print(card.get_year())             # 2030
print(card.get_month())            # 12
