Average of List elements returns error


#1
xfile=open("mbox-short.txt")
numlist=list()
sum, count =0,0
for line in xfile:
    line=line.rstrip()
    if line.startswith("X-DSPAM-Confidence:"):
        words=line.split()
        num= float(words[1])
        sum=sum+num
        count=count+1
        numlist.append(num)
print sum/count
print sum(numlist)/len(numlist)

This program returns the error, due to the last line

Traceback (most recent call last):
  File "C:\Users\rahulgenesis\OneDrive\notes\Python Notes\files\8 average of numbers using list.py", line 13, in <module>
    print sum(numlist)/len(numlist)
TypeError: 'float' object is not callable

The objective of the program is to calculate the average of the extracted elements (spam score) from a mail box. I am trying to do it using list, after storing the elements inside the list. I am kinda feeling that this error is due to the fact that all the elements in the list are not of the same type...?

Please help...
