Python Program Design: Building a Shoe Store Catalog Search

Designing the Shoe Class

• 💡 A class definition is created to model shoes, named Shoe.
• 🔑 The __init__ method initializes attributes for each shoe: name, color, brand, and size.
• 🎯 These attributes store the initial values passed as parameters, using self.attribute = value.

Creating and Storing Shoe Objects

• 👟 An example Shoe object, 'Air Jordans' (black and red, Nike, size 8), is created to test the class definition.
• 📚 Shoe objects are stored in a list to represent the store's catalog, allowing for iteration.
• 📦 Class definitions are placed in their own module (shoe.py) for better organization and reusability, requiring import shoe and shoe.Shoe to access the class.

Implementing Search Functionality

• 🔍 The initial search logic focuses on filtering by brand.
• ⚠️ Variable shadowing is identified and resolved by renaming the loop variable from shoe to avoid conflict with the shoe module.
• 💬 Printing a shoe object directly shows its memory address; custom display requires accessing individual attributes.

Enhancing Search Capabilities

• 🎯 Search is enhanced to perform partial matches on the name and color attributes using the in operator.
• ⚙️ A case-insensitive match is implemented by converting both the keyword and attribute values to lowercase using the .lower() method.
• 🚀 The foundation is laid for more advanced features like multi-keyword searches and filtering by shoe size.
