This assignment will get you up to speed on some Python3 basics, which should help with learning Django later this semester that is built upon Python and will require you to write your web server backend in Python3.

We are using Python3 vs Python2 as it is where the industry is going and projects are starting to support both with the expectation that a shift to Python3 will happen soon.

This problem is inspired by: https://www.hackerrank.com/challenges/defaultdict-tutorial

Your method should take in values representing the following:

• aList = list of strings

Your method called stringCount should print out a sorted alphabetically list of the strings and the number of that string in the list separated by a space on each line.

For an example:

alist = ["Hello", "Hello", "Bob"]
stringCount(alist)

This should print:

Bob 1
Hello 2

This problem is inspired by: https://www.hackerrank.com/challenges/introduction-to-regex

Your method isFloat should take in a string value and return a boolean if the given string is a Float or not. It is recommended that you leverage the python regular expression library for this; however, it is not required.

isFloat("4.0O0") #returns False
isFloat("-1.00") #returns True
isFloat("+4.54") #Returns True

The last part of this assignment will be building a simple linked list with two python3 classes called LinkedList and Node. We won't be directly interacting with the Node class so you could call that whatever you wish; however, that's what I would recommend. For reference you should look at the documentation for classes in Python3: https://docs.python.org/3/tutorial/classes.html

An example of your linked list class being used:

ll = LinkedList()
ll.insert(1)
ll.insert(2)
ll.printLL()
ll.delete(2)
ll.printLL()
if ll.search(2):
	print("Value 2 found")
else:
	print("Value 2 not found")
if ll.search(1):
	print("Value 1 found")
else:
	print("Value 1 not found")
ll.insert(4)
ll.printLL()
print(str(ll.size()))

This simple test of your LinkedList should output the following:

2 1
1
Value 2 not found
Value 1 found
4 1
2

If you haven't already create your CINS465 repo through the form on my website, you'll need the GitHub Token given out in lecture to do so.

The code should be submitted to your CINS465 on a branch named assignment1, make sure your case is identical for your branch or I may not find/grade your submission. To do this you can do the following in your repo directory, it assumes you want to add all the code in the directory:

git checkout -b assignment1 #create branch and switch to it
git add -A #add all
git commit -m "Assignment 1 Submission" #Commit changes to branch
git push --set-upstream origin assignment1 #Push code up to assignment2 branch on remote

Your assignment1.py file will be loaded into a grading script python file as an external library and directly called. Your submission should just provide the correct implementation. Unless the function or method of the class explicitly should print your code should have no debugging output.
