So, I've edited the nester module. I then referred to chapter 2, and built my distribution and installed it to my local copy of python.

Here's my updated program:
import nester

man = []
other = []

try:
    data = open('sketch.txt')
    for each_line in data:
        try:
            (role, line_spoken) = each_line.split(':', 1)
            line_spoken = line_spoken.strip()
            if role == 'Man':
                man.append(line_spoken)
            elif role == 'Other Man':
                other.append(line_spoken)
        except ValueError:
            pass
    data.close()
except IOError as oops:
    print('The datafile is missing! ' + str(oops))

try:
    with open('man_data.txt', 'w') as man_file, open('other_data.txt', 'w') as other_file:
        print_lol(man, fh=man_file)
        print_lol(other, fh=other_file)
        
except IOError as err:
    print('File error: ' + str(err))

But, I'm getting this 'print_lol' is not defined! I have a feeling that I'm just overlooking some small typo or missing one simple line of code...

Ok.... I decided to read a little further back in Chapter 2. Yep, found my problem.

I need to either specify that print_lol comes from the nester module:
nester.print_lol(man, fh=man_file)

Or, when I 'import nester', I can specify the 'print_lol' function there:
from nester import print_lol

The whole 'namespace' thing. This time I read it and took some time to think about it a little more and now understand and "agree" with the idea of using the 'nester.print_lol' way.
