Hi Maggie,
I see you have already gotten a lot of useful help.
One additional suggestion would be to use a different
variable name other than 'sum' as sum is a Python
built-in functio

Hi
sum = 0
for item in readData:
try:
sum += int(item)
except ValueError:
print "Oops! That was no valid number. Instead it was:", item
So you mean to say this would ignore the bad data and continue processing ?

Tighten the area included in the try...except:
sum = 0
for item in readData:
try:
sum += int(item)
except ValueError:

A slightly better way to write this:
test = open("test.txt", "r")
#set up a sum
code practice:
test = open ("test.txt", "r")
readData = test.readlines()
#set up a sum
sum = 0;
for item in readData:
sum += int(item)
print sum
test file looks something like this:
34
23
124
432
12
when i am trying to compile this it gives me the error: invalid
literal for int() with b
16 matches
