I am new to python. I like to calculate average of the numbers by reading
the file 'digi_2.txt'. I have written the following code:
def average(s): return sum(s) * 1.0 / len(s)
f = open ("digi_2.txt", "r+")
list_of_lists1 = f.readlines()
for index in range(len(list_of_lists1)):
tt = li

Since you're new to Python, I won't try to supply you an answer using
list comprehensions, since you've probably not learned them yet.

Thanks for the help.
You're welcome.
You replied privately, instead of including the list, so I'm forwarding
the response so everyone can see it. You also top-posted, so the
context is backwards.
After running your code, I am getting the follow
I have an elementary question provoked by another post today.
1. Is it the case that ALL imported data from a file is a string?
2. Does this therefor imply that said data has to be processed
appropriately to generate the data in the form required by the program?
3. Are there defined procedures

No, the imported data is a module. For example
import sys
print type(sys)
At this point, sys is a object of

Assuming you mean data read from a file rather than modules imported
using 'import' then the answer is 'it depends'.

Dear list,
I have been trying to understand out how to use iterators and in
particular groupby statements. I am, however, quite lost.
I wish to subset the below list, selecting the observations that have
an ID ('realtime_start') value that is greater than some date (i've
used the variable name m

groupby is a very specialist function which is not very intuitive to
use. Sometimes I think that groupby is an excell

You can do it with groupby like so:
from itertools import groupby
from operator import itemgetter
maxDate = "2013-03-21"
mmax= list()
obs.sort(key=itemgetter('date'))
for k, group in groupby(obs, key=itemgetter('date')):
group = [dob for dob
