How do you sort the contents of a .txt file in numerical order?

I have some trouble making a code that arranges a .txt file in numerical order.

The problem I'm having is when ordering numbers 77, 45, 85, 100 in the .txt file it orders it as 100, 45, 77, 85; 100 being the lowest.

Not sure how I would correct that as I want 100 to be the highest.

This is what I have so far:

import csv
import operator


sample = open("score.txt")
csv1 = csv.reader(sample, delimiter=',')
sort = sorted(csv1, key=operator.itemgetter(1))
for eachline in sort:
    print eachline

Solution

Like budder says, try to convert your elements to int or float. "It's sorting in an unexpected manner because they are strings." Assuming that you are working with integers you can change your key in sorted() func:

sort = sorted(csv1, key=lambda x: int(x[1]))
