created that solved for the mode,mean, and average of a set of numbers it
actually worked great..if anyone can give me any ideas on this program i am
doing now it would be appreciated.I keep would like to understand why on the
last portion it returns an error.thank you.import shelveimport stringUNKNOWN =

lookup(self, string):list = []for key in self.shelve.keys():e =
self.shelve[key]if cmp(e, string) == 0:list.append(e)
return(list)# if not being loaded as a module, run a small testif __name__ ==

Hi, I have problem here...I am writing a program but I am getting stucked at
how to solve the mode of a series of numbers...any ideas???following is the
program:def mode(data):num=0count=0mx=0mode=0for i in data:
if num!=data[i]:num=data[i]count=count+1
else :count=count+1if countmx:mx=countmode=num
print 'The mode is: ',modedef median(lst):x=len(data)y=x/2
print 'The median is: ',data[y]def getlst():num=[]while True:
s=raw_input('please enter a series of number to evaluate')if
s=='':breaknum.append(eval(s))return numdef avg(y): sum(y)
print'the average is: ', sum/len(y)data=getlst()median(data)avg(data)___
