Languages with Inheritance include Java, JavaScript, Python, PHP, Scala, TypeScript, Dart, Groovy, CoffeeScript, Pug, SystemVerilog, Twig, Apex

Example from JavaScript, TypeScript:

class B {}
class A extends B {}

Example from Python:

class SumComputer(object):
   def __init__(self, a, b):
       self.a = a
       self.b = b
   def transform(self, x):
       raise NotImplementedError
   def inputs(self):
       return range(self.a, self.b)
   def compute(self):
       return sum(self.transform(value) for value in self.inputs())
 class SquareSumComputer(SumComputer):
     def transform(self, x):
         return x * x
 class CubeSumComputer(SumComputer):
     def transform(self, x):
         return x * x * x
