+## 🚫 Anti-Patterns
+
+This section lists some common design patterns that are **not recommended** in Python and explains why.
+
+### 🧱 Singleton
+**Why not:**
+- Python modules are already singletons — every module is imported only once.
+- Explicit singleton classes add unnecessary complexity.
+- Better alternatives: use module-level variables or dependency injection.
+
+### 🌀 God Object
+**Why not:**
+- Centralizes too much logic in a single class.
+- Makes code harder to test and maintain.
+- Better alternative: split functionality into smaller, cohesive classes.
+
+### 🔁 Inheritance overuse
+**Why not:**
+- Deep inheritance trees make code brittle.
+- Prefer composition and delegation.
+- “Favor composition over inheritance.”

 It decouples the creation of a complex object and its representation,
 so that the same process can be reused to build objects from the same
 family.
 This is useful when you must separate the specification of an object
 from its actual representation (generally for abstraction).
