You don't need to fetch
I can't recall how to do this:
I want:
a = [int(x) for x in tmp]
but, my tmp has some empty elements, so it fails...
Therefore I want to be able to say:
a = [int(x) for x in tmp IF x in tmp]
I know there's a way! Ive seen it before, but now cannot find it! 'if'
is a pretty generic thing to se

learning python and fix the file

That's almost right, except it checks the wrong thing. Try

I also noted, if I used:
tmp = data[6].strip().split()
rather than:
tmp = data[6].strip().split(' ')
I eliminated the 'empty' elements...

good enough, i suppose i can use a try, except to test if i am online and
from that have a true / false.
That is what i was looking for. I just didn't think it necessary to pull a
webpage every 20 minutes.
thanks

I know this seems elementary, but if I write a program and save it as a .py
file, how do I then run that program on the command line or in the Python Shell
(GUI)? Or is there something I'm missing? I swear I was able to do this once,
and now I can't remember what I did...

Jessica,
Assuming you have python installed on your system (Windows?, *nix?),
then all you have to do is double click the .py file and it will run.
If you want, you can run it from the command line:
C:\> python yourfile.py

x will always be in tmp - thats where it comes from!
You want to check if its non null.
a = [int(x) for x in tmp if x]

Just type "python script.py" at the OS prompt
Or in *nix you can just type script.py if you havbe a shebang

No its a programming construct found in Function programming
languages such as Haskell (Python is partially functional in nature).
Basically a list comprehension builds a list

I am wondering how look for a key in a dictionary, given a value.
I have a dictionary similar to this:
a = { 'a1':1, 'a2':2, 'a3':3, 'a4'.:4}
If I have the value of 2, how would I look at the dictionary to turn
that into 'a2'.

You have to search the values. This
Hi Dotan,
Just for reference, the weirdness that you're seeing before the email
addresses in your text file are "MIME-encoded" strings.

Concretely, the string

Hello, I'm trying to calculate an average for columns in my
array(data), there's a catch though, I want to create a new array of
shorter length (NOTE: this crashes at line 8):
1) tinit = data[0][0]
2)for d in data:
3)if d[0] <= tinit+60:
4)sum = sum+d
5)else:
6)
Oops, I meant it crashes at line 7..

Thanks for the feedback,
The average was a little bit goofed up. Here's what I have now:
for d in data:
if d[0] <= tinit+60:
d = column_stack(d)
cnt=cnt+1
sum = sum+d
else:
avg = sum/cnt
if init==0:
newData = av
Ug,
It still doesn't make sense due to the sum/cnt where cnt is just an
int, and sum is a 1-dimensional array!
I'm missing something here about working with numpy arrays...

It aint pretty! And if I had just walked away, it probably would've
taken half the time in the morning, but here's what I've come up with
(any suggestions for improvements, or course are welcome):
for d in data:
w = len(d)
if d[0] <= tinit+60:
d = column_stack(d)
And of course, thanks all!
