what are Constructors in python
Python Constructors:
Python facilitates a special type of method, also called as Python Constructors, to initialize the instance members of the class and to verify enough object resources for executing any startup task.
Types of Constructors:
- Parameterized Constructor
- Non- Parameterized Constructor
Features of Python Constructors:
- In Python, a Constructor begins with double underscore (_) and is always named as __init__().
- In python Constructors, arguments can also be passed.
- In Python, every class must necessarily have a Constructor.
- If there is a Python class without a Constructor, a default Constructor is automatically created without any arguments and parameters.
Example:
class Employees():
def __init__(self, Name, Salary):
self.Name = Name
self.Salary = Salary
def details(self):
print "Employee Name : ", self.Name
print "Employee Salary: ", self.Salary
print "\n"
first = Employees("Khush", 10000)
second = Employees("Raam", 20000)
third = Employees("Lav", 10000)
fourth = Employees("Sita", 30000)
fifth = Employees("Lucky", 50000)
first.details()
second.details()
third.details()
fourth.details()
fifth.details() |
