Python sort list in Python 3
This is a second request as the first request was filled, but it does not meet the objective of what I am trying to produce and as well produces a blank output I appreciate the first attempt at helping me with this code, but unfortunately it is not working and does not produce the output that i need.

Each line in this file has four pieces of information, separated by tabs.
Last name t First name t Date took office t Date left office n

The four pieces of information are:

I need help with a python 3 script that will read from presidents.txt and produce 3 seperate .txt files
The first output file needs to be named same_order.txt, thus far my pseudo code is:
open the input file
open the output file
for each line in the input file:
call function to write out the sentence
close the input file
close the output file
with an output of:
Abraham Lincoln was president from 3/4/1861 to 4/15/1865.
Andrew Jackson was president from 3/4/1829 to 3/4/1837.
Andrew Johnson was president from 4/15/1865 to 3/4/1869.
the second output file needs to be named last_name.txt and have an output like this:
John Adams was president from 3/4/1797 to 3/4/1801.
John Quincy Adams was president from 3/4/1825 to 3/4/1829.
Chester A Arthur was president from 9/19/1881 to 3/4/1885.
In the cases where the last names are the same, the Johnsons, the Adams’s, and the Bushes, sort by first name
The third and final output file needs to be named inauguration.txt with an output that looks like this:
George Washington was president from 4/30/1789 to 3/4/1797.
John Adams was president from 3/4/1797 to 3/4/1801.
Thomas Jefferson was president from 3/4/1801 to 3/4/1809.
for both William Henry Harrison and James A Garfield who served less than one year as president. I should include the month that the president took office as the order of data, not just the year.
I need to mainly keep the data ordered within code, rather than trying to rearrange the input data file
Expert Answer
import datetime as dt
import operator
class president:
lastname=”
firstname=”
dto=dt.datetime.today().strftime(“%m/%d/%Y”)
dlo=dt.datetime.today().strftime(“%m/%d/%Y”)
pr=[]
i=0
with open(‘presidents.txt’) as f:
for line in f:
obj=president()
list=line.split(“t”)
obj.lastname=list[0];
obj.firstname=list[1];
pr.append(obj.lastname)
pr.append(obj.firstname)
date_split=list[2].split(“/”)
obj.dto=dt.datetime(int(date_split[2]),int(date_split[1]),int(date_split[0]),0,0)
pr.append(obj.dto)
date_split=list[2].split(“/”)
obj.dlo=dt.datetime(int(date_split[2]),int(date_split[1]),int(date_split[0]),0,0)
pr.append(obj.dlo)
i=i+1
map(operator.itemgetter(0), pr)
map(operator.itemgetter(1), pr)
map(operator.itemgetter(2), pr)
map(operator.itemgetter(3), pr)
file_path=’same_order.txt’
orig_stdout = sys.stdout
f = file(file_path, ‘w’)
sys.stdout = f
print sorted(L, key=operator.itemgetter(1))
sys.stdout = orig_stdout
file_path=’last_name.txt’
orig_stdout = sys.stdout
f = file(file_path, ‘w’)
sys.stdout = f
print sorted(L, key=operator.itemgetter(0))
sys.stdout = orig_stdout
Please slightly modify this to get the answer as i need more time to submit,
