It is really simple. Can you post the code you've written so far?

Untested:

with open("numbers.txt", "r") as f:
print sum(int(x) for x in f)

thats what i have so far --

#!/usr/bin/python

import os.path

#open up the file
formisanoOpen = open("formisano_num.txt", "r")

#read in all the data into a list
readData = formisanoOpen.readLines()

#set up a sum
sum = 0;

#begin a loop
for trial in readData:

#the next line is indented (YA doesn't indent)
sum += int(trial)

#loop is over, so unindent
#report the sum
print sum


end

but it doesnt want to run for some reason....

Could you let us know what kind of error you are getting?

I don't know if this is your error, but this line won't run:

readData = formisanoOpen.readLines()

Since Python is case-sensitive, you would need a lower-case 'l' in
'readlines()' -- perhaps that would solve your problem?

in the terminal i get a very strange "permission denied" error that
might not have anything to do with the code. I checked permissions for
the file and they are set to "read and write" so, again, I am really
not sure what going wrong.

Try:

python myfile

Or

chmod +x myfile
./myfile

try it where? code or terminal?

thanks so much?

Please try these in the terminal -- the permission denied error may be due
to your shell not being able to execute the Python script, instead of your
Python script not being able to open the data file.

are the following --

File "running_sum_formisano.py", line 18

IndentationError: expected an indented block

Have you even read the Python tutorial? Please do so if you haven't already..
Indent the line by 4 spaces.
