Module $2$ Required Coding Activity

Introduction to Python $($Unit $2)$ Fundamentals

Be sure to complete all tutorials and practice prior to attempting this activity.

Important Assignment Requirements

NOTE: This program requires creating a function using def and return, using print output, input, if$,$ in keywords, $.$append$(),.$pop$(),.$remove$()$ list methods. Be sure to include your full name in the prompts. See the example input below for more detail.

Program: list$-$o$-$matic

This program takes string input and checks if that string is in a list of strings

if string is in the list it removes the first instance from list

if string is not in the list the input gets appended to the list

if the string is empty then the last item is popped from the list

if the list becomes empty the program ends

if the user enters "quit" then the program ends

program has $2$ parts

program flow which can be modified to ask for a specific type of item. This is the programmers choice. Add a list of fish, trees, books, movies, songs.... your choice.

list$-$o$-$matic Function which takes arguments of a string and a list. The function modifies the list and returns a message as seen below.

Flowchart of List$-$o$-$Matic

$[]$ initialize a list with several strings at the beginning of the program flow and follow the flow chart and output examples

example input$/$output

Welcome, $[$YOUR NAME GOES HERE$].$ Look at all the animals $[\text{'}$cat$\text{'},$ 'goat', 'cat'$]$

enter the name of an animal: horse

$1$ instance of horse appended to list

Welcome, $[$YOUR NAME GOES HERE$].$ Look at all the animals $[\text{'}$cat$\text{'},$ 'goat', 'cat', 'horse'$]$

enter the name of an animal: cat

$1$ instance of cat removed from list

Welcome, $[$YOUR NAME GOES HERE$].$ Look at all the animals $[\text{'}$goat$\text{'},$ 'cat', 'horse'$]$

enter the name of an animal: cat

$1$ instance of cat removed from list

Welcome, $[$YOUR NAME GOES HERE$].$ Look at all the animals $[\text{'}$goat$\text{'},$ 'horse'$]$

enter the name of an animal: $(<--$ entered empty string$)$

horse popped from list

Welcome, $[$YOUR NAME GOES HERE$].$ Look at all the animals $[\text{'}$goat$\text{'}]$

enter the name of an animal: $(<--$ entered empty string$)$

goat popped from list

Goodbye!

example $2$

Welcome, $[$YOUR NAME GOES HERE$].$ Look at all the animals $[\text{'}$cat$\text{'},$ 'goat', 'cat'$]$

enter the name of an animal: Quit

Goodbye!

# $[]$ create list$-$o$-$matic as a function and call it

# $[]$ be sure to include your spelled$-$out name in the welcome prompt

# $[]$ you are welcome to use any list you like for list$-$o$-$matic, does not have to be animals
