Description

In this homework you will read and parse a file with text and numbers. You will write three functions. First write a function to extract the numbers in the file and return the sum of the numbers. Then write a function to return a count of the number of times a given word appears in the file. Count the word even if it starts a sentence (begins with a capital letter). Don’t count the
word if it has additional characters after it (like an ‘s’). Finally, write a function to return a list of all of the URLs in the file of the form something.something.something like “www.cnn.com”. The something should be any number of alphanumeric characters (but at least one alphanumeric character).
Data Files
We provide two files for this assignment.
• Sample data: http://py4e-data.dr-chuck.net/regex_sum_42.txt (There are 90 values with a sum=445833)
• Actual data: http://py4e-data.dr-chuck.net/regex_sum_132198.txt (There are 82 values and the sum ends with 566)
Open these links open in a new window. Make sure to save the file into the same folder as you will be writing your Python program.

Data Format
The file contains text from the introduction of a textbook except that random numbers are inserted throughout the text. Here is a sample of the output you might see:
Why should you learn to write programs? 7746
12 1929 8827
Writing programs (or programming) is a very creative 7 and rewarding activity. You can write programs for many reasons, ranging from making your living to solving
8837 a difficult data analysis problem to having fun to helping 128 someone else solve a problem. This book assumes that everyone needs to know how to program …
The sum for the sample text above is 27486. The numbers can appear anywhere in the line. There can be any number of numbers in each line (including none).

Handling the Data
1) Write a function sumNums(filename) to read from a file when given the filename and look for integers (that are not phone numbers) using the re.findall(), and then convert the extracted strings to integers and return the sum of the integers.
2) Write a function countWord(filename,word) to return a count of the number of times a specified word appears in a file. It should match the word when it starts a sentence also (starts with a capital letter). It should not match any additional letters after the word. For example, if called on “computer” it should match “Computer” and “computer” but not “computers”. For file regex_sum_42.txt it will return 15 when called with the word “computer”.
3) Write a function listURLs(fileName) to return a list of the URLs in the file when given the file name. It should match URLs like www.cnn.com. It doesn’t have to return the http:// part or the https:// part of the URL, but it can. For file regex_sum_42.txt it will return a list of three URLs.
Use hw6.py to start. It has unit tests to test your code. Turn in a link to your github repo.
Grading
• 15 points for passing the test_sumNums1
• 15 points for passing the test_sumNums2
• 10 points for passing the test_countWord with “computer”
• 5 points for passing one of our tests that you haven’t been given for countWord.
• 10 points for passing the test listURLs.
• 5 points for passing one of our tests with listURLs that you haven’t been given for listURLs.
