Learning IronPython #9: Classes

I can declare a class in IronPython as follows:

# File name: MySimpleMathClass.py
# Instantiate an instance of this class by calling the following:
# import MySimpleMathClass
# someObjectVariable = MySimpleMathClass.MySimpleMath()
# or similar.
class MySimpleMath:
# You must define an __init__ method (similar to a constructor).
# The first argument must be to self (the class instance).
def __init__(self):
# The pass keyword is a do-nothing statement
# (similar to an empty constructor).
pass
# The first argument to all class methods must
# be to self (the class instance).
# Invoke class methods by calling the following:
# someObjectVariable.add(10, 5)
# or similar.
def add(self, a, b):
return a + b
def subtract(self, a, b):
return a - b
def multiply(self, a, b):
return a * b
def divide(self, a, b):
return a / b

I can then create an instance of that class and use its methods from the console as follows:

>>> import MySimpleMathClass
>>> MySimpleMathClassInstance = MySimpleMathClass.MySimpleMath()
>>> print MySimpleMathClassInstance.add(10,5)
15
>>> print MySimpleMathClassInstance.subtract(10,5)
5
>>> print MySimpleMathClassInstance.multiply(10,5)
50
>>> print MySimpleMathClassInstance.divide(10,5)
