# Replace "Your Name" with your name :)

my_name = "Your Name"

# I'm hoping this will be pretty straightforward.

# First, this little bit of code will make sure you have

# Project Gutenberg's "Adventures of Sherlock Holmes" text

# file in the same directory (folder) as this quiz file.

# It's designed so that you only download it once regardless

# of how many times you run this file.

import os.path as path

import requests

if not path.isfile('sherlock.txt'):

    response = requests.get('https://www.gutenberg.org/files/1661/1661.txt')

    with open('sherlock.txt', 'w') as sherlock:

        sherlock.write(response.text)

# Here's the whole problem this week: open that file, read it,

# and count how many times "Moriarty" appears, how many times

# "Watson" appears, how many times "Adler" appears, and finally

# how many times "Holmes" appears.

# The values should be in a dictionary called "counts" with 

# keys for (at least) Moriarty, Watson, Holmes, and Adler.

# IMPORTANT: if one of those names doesn't appear, then the count 

#            should be zero for that name

# Hints: 1. Python For Everybody walks through an example using

#        a dictionary as a counter. You may or may not fund that useful.

#        2. Think about how you might find these names: could they

#        appear separated by whitespace, or are there other characters

#        (like punctuation) that might also be present? Is there a

#        solution where this doesn't matter?

#        3. There's more than one way to approach this, but the split

#        method of the re (regex) package might be useful. So might findall.
