Dead Code in Python: What It Is and How to Remove It
Dead code is code that is defined but never executed — unreachable branches, unused functions, commented-out blocks. It inflates the codebase and hides real bugs.
❌ Code with Dead Branch
def get_discount(user_type):
if user_type == 'premium':
return 0.2
elif user_type == 'premium': # Duplicate — unreachable!
return 0.3
return 0.0✅ Cleaned Up
def get_discount(user_type):
if user_type == 'premium':
return 0.2
return 0.0💡
