I need to write a class, Numbers, with methods addNumbers and currentSum, that prints the current sum. Eg.:
numbers = Numbers()
numbers.addNumber(3)
numbers.addNumber(2)
print numbers.currentSum()
should print 5
I have made a class:
class Numbers:
def __init__(self, numbers):
self.numbers=addNumbers
return numbers.currentSum()
Numbers=Numbers()
A hint, anyone?
class Numbers:
def __init__(self):
self.__sum=0
def addNumber(self, number):
self.__sum += number
def currentSum(self):
return self.__sum
Hints:
currentSum() methodaddNumber() methodaddNumber() will need to keep track of numbers across method calls. Use a list.More reading on methods: What is a "method" in Python?
class Numbers(object):
def __init__(self):
self.sum = 0
def addNumber(self, n):
self.sum += n
def currentSum(self):
return self.sum
class X(object):instead.class X:is an old style class.. Here are the differences.
