was trying to plug in the sum for the loop..but for some reason it
doesnt want to work --
#!/usr/bin/python
import os.path
#name of output file
filename = "OUTPUT.txt"
#open the file
formisano = open ("test.txt", "rU")
#read in all the data into a list
readData = formisano.readlines()
sum = 0
count = 0
FILE = open(filename, "w")
for item in readData:
count = count + 1
sum = sum + (int(item) * int(item))
tmp_string = str(count) + ' ' + item + ' '+ sum
print >> FILE, tmp_string,
else:
print 'The loop is finito'
