Assignment: phoney Module, v$\mathrm{.}2$

CIT $30900$

What$$s the Big Idea?

Update your existing phoney module to add additional cleaning logic to your clean$\_$phone$\_$numbers$()$ function.

IMPORTANT: Use Git to Branch Your Work

PRIOR to starting new code on this project, follow the instructions for using Git from the CIT $30900$ workbook.

You MUST:

$1.$ Create a local Git repository that contains all your files from v$\mathrm{.}1$

$2.$ Add all your files and create a commit

$3.$ Create a new branch of the repository named v$1$ that preserves your work from the previous assignment

$4.$ Switch back to the main branch and make your updates to the project as specified below

You MAY $($but are not required to$)$:

$1.$ Create a remote repository on GitHub.com

$2.$ Push your code to your remote repository with the command

git push origin $--$all

$3.$ REMEMBER: Your GitHub.com repository should be set to PRIVATE

Obtain New Test Data

You are building on your previous version of this project.

HOWEVER, you MUST obtain a new set of phone numbers to use with this new version of your program!!

Instructions to obtain this data are on Canvas.

Updated Requirements

You will update your clean$\_$phone$\_$numbers$()$ function according to the following requirements:

Original Requirements

$1.$ clean$\_$phone$\_$numbers$()$: Accepts a list of phone numbers and returns a list of phone numbers that contain precisely $10$ digits. It removes any special characters from the numbers $($parenthesis$,$ hyphens$)$ and removes any number that is not precisely $10$ characters long

Additional Requirements

In North America, phone numbers consist of three parts: ABB$-$CDD$-$ZZZZ where:

$$ ABB: the area code

$$ CDD: the exchange

$$ ZZZZ: the station code$/$line of the individual

Using regular expressions, you should further filter the phone numbers according to the following rules:

$1.$ The FIRST digit in the area code $($labeled $$A$$ in the pattern above$)$ CANNOT be a $1$ or a $0.$

$2.$ The FIRST digit in the exchange $($labeled $$C$$ in the pattern above$)$ CANNOT be a $1$ or a $0.$

$3.$ The EXCHANGE $($labeled $$CDD$$ in the pattern above$)$ CANNOT be equal to $555$

Hints

$$ Do not try to accomplish all of the filtering in a single regular expression. Use multiple expressions to filter the list of phone numbers.

o It is possible to do this all in one, but that$$s not important right now. The purpose of this assignment is to learn how to apply regular expressions $$ not become the world$$s foremost expert on them.

Commit and Branch!

When you are finished with the updates to your program, do the following:

$1.$ Add and commit your files using Git

$2.$ Create another new branch $($named v$2)$ that preserves your work at this point in the program

$3.$ Switch back to the main branch

$4.($Optional$)$ Push all your branches to GitHub.com with the command git push origin $--$all

Complete instructions can be found in the CIT $30900$ workbook.

Submission Instructions

To submit, zip the following files and attach them to Canvas:

$1.$ phoney.py

$2.$ index.py

$3.$ phone$\_$numbers.csv $($NOT the sample CSV provided to you$)$

Rubric

Requirement Points Available

Regular expression to find $0$ or $1$ at the start of the area code $5$

Regular expression to find $0$ or $1$ at the start of the exchange $5$

Regular expression to find exchanges that are $5555$

Total: $15$
