Unicode characters for telugu:
http://en.wikipedia.org/wiki/Telugu_alphabet#Unicode
On python 3.x,
>>> import re
>>> a='ఏఐఒ ఓఔక ఞతణథ'
>>> print(a)
ఏఐఒ ఓఔక ఞతణథ
>>> re.split('[^\u0c01-\u0c7f]', a)
['ఏఐఒ', 'ఓఔక', 'ఞతణథ']
Similar logic can be used for any other Indic script.

Re: [Tutor] summary stats grouped by month year
Python generally comes with support for sqlite3. you can store your date in to sqlite db and then try running sql query for finding of the details. select year, sum(MeanRain) where year='1972' group by year; select month, sum(MeanRain) where month='Jan' group by month; ** Not sure regarding the exact sql query. sum function and 'group by' is important.

print('Invalid input')

There are few more cases where above may fail. In that case you may want
to use re module instead.
e.g.
@test_decorator # this is test comment.
because all of our decorators start with the @ symbol. The problem
I'm having is that the email addresses that are included in the
comments are getting included in the list that is getting returned.
I was thinking I could do a candidate_line.find(".com") to set the
email addresses apart, but how do I tell the computer to not include
the lines it finds with ".com" in them in the list?
The part of my code that I'm hoping to include this in looks like this:
#parse out the names of the decorators from those lines
return_decorators= []
for ele in subset_lines:
candidate_line, line_number = ele
candidate_line = candidate_line.strip()

You can try read instead of readlines.
Something like...
print 'Number of lines till 1000th character:',
len(open('/tmp/new.txt','r').read(1000).split('\n'))

If the input has more than one ',', e.g. '1,2,3'. You may like to use 'split'
