Class inheritance


In this section, we will learn about inheritance. Inheritance allows us to inherit methods and attributes of the parent class. By inheritance, a new child class automatically gets all of the methods and attributes of the existing parent class. The syntax is given as follows:

class DerivedClassName(BaseClassName):
   <statement-1>
   .
   . .
   <statement-N>

If you remember, in Chapter 10, File Handling and Exceptions, we had inherited the built-in class exception. Starting with the existing code, let's make the instructor class, which would inherit the method of the Leapx_org class. Refer to the code in classinheri1.py:

class Leapx_org():
   mul_num = 1.20
   count= 0
   def __init__(self,first,last,pay):
      self.f_name = first
      self.l_name = last
      self.pay_amt = pay 
      self.full_name = first+" "+last
      Leapx_org.count = Leapx_org.count+1

   def make_email(self):
      return self.f_name+ "."+self.l_name+"@xyz.com"

   def incrementpay(self...
