Hi
I have a function for calculating the standard deviation of a list. I was wanting to create this as an object and inherit from pythons list object.
I'm pretty new to the whole OOP concept, can someone please have a look at my code to see why it prints an address rather than a value and where I'm messing this OOP thing up.
Thanks
-
class StandardDev(list):
-
def __init__(self, theList):
-
self.theList = theList
-
-
def standardDev(self):
-
import math
-
sums = 0
-
n = len(self)
-
#Calculate the mean average
-
ma = (1/float(n))*sum(self)
-
for i, j in enumerate(self):
-
sums += ((self[i]-ma)**2)
-
return round(math.sqrt((1/float(n))*(sums)),2)
-
-
-
a = (5,6,8,9)
-
-
b = StandardDev(a)
-
print b.standardDev
