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:

Hi
I am just a python beginner
What you need is exceptions
http://docs.python.org/tutorial/errors.html
something on the lines of since you expect a integer and you wnat to catch the
exception
... try:
... sum = 0;
... for item in readData:
...sum += int(item

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
89 matches
