+# Special cases aren't special enough to break the rules.
+
+Consider the `capitalize_words()` function below. It uniformly uses the `.capitalize()` method for all words in a string, regardless of their original case.
+
+This approach exemplifies the principle by avoiding special handling for cases like acronyms or words that are already capitalized.
+
+This uniform treatment keeps the code simple and consistent, highlighting the elegance of Python's design philosophy. 🐍 😁
+
+```
+def capitalize_words(s):
+    # no extra ifs, one consistent interface
+    return ' '.join(word.capitalize() for word in s.split())
+
+print(capitalize_words("hello world"))  # Outputs "Hello World"
+print(capitalize_words("python is FUN"))  # Outputs "Python Is Fun"
+```
