Python Programming - Getting Started

This bootcamp is part of the Programming / CS Bootcamps

For a video explaining how to get started with this bootcamp, see https://www.youtube.com/watch?v=uLnhcCZS4-Y&t=424s

Getting Started

1. Reading - start reading through at least one of the following before you start working on the programming problems.
   1. Automate the Boring Stuff with Python - suitable for people with very limited programming experience, this is the text that is being followed for our CS 151 course (as of 2019)
   2. Think Python - suitable for people with very limited programming experience, not very deep
   3. LearnXinYminutes - quick review once you are familiar with the basics
   4. Python.org tutorial - good for those with programming experience already
2. Work on solving these problems - https://www.hackerrank.com/domains/python. Start with the first problem and work your way up from there.
3. Get Python installed on your computer - download the latest Python3 version at https://www.python.org/downloads/. Having python3 installed on your computer allows you to debug much quicker.
4. If you are a current or incoming ISU student, or an ISU alumni, sign up for the ISU CS Mattermost at https://judy.indstate.edu. Note that you need to use your @sycamores.indstate.edu email address to sign up. Look for the Python Programming Channel (direct link is https://judy.indstate.edu/isu-cs/channels/python-programming). When asking about the hackerrank problems make sure to refer to them using the title hackerrank gives them.

Let's see how far you can get with solving the hackerrank problems! Good luck!

List of Problems

Here are problems to work on from the hackerrank set. Note that you should work on more than just this set, but these are ones we are ready to help you solve!

Basic Python

These problems are all pretty basic - require a single loop, if statement, etc. They are good when you are just getting started with Python.

• Py Hello World
• Py If Else
• Python Arithmetic Operators
• Python Loops
• Swap Case

For a bit more practice with basic problems, try out more of the problems that are listed as "Easy". Once you have completed the once listed in this section you should be ready to complete more of the "Easy" problems on your own.

• Write a Function
• Text Wrap

A Bit More Involved

These problems require nested loops, working with lists of lists, reading a problem statement that takes more time to understand, or other things that are the next level of difficulty. Solve all of the Basic Python problems before starting on these.

• Nested List
• List Comprehensions
• Merge the Tools
• No Idea
• Validating Credit Card Number
• Words Score
• Compress the String
• Word Order

And a Bit More

These problems are still a bit more involved. Some require some abstract thinking about the problem, a programming "trick", or other key insight. Note that at this point you are working on problems such that some of the lab assistants in the unix lab may not have solved these problems. This is where you want to be at - you have mastered the basics and are working on problems independently!

• Validating Postalcode
• Matrix Script
• Maximize It

After That

If you are able to do all of the problems above, then you don't need us to give you lists of problems any more. You can pick problems to work through on your own. Some suggested places with problems are as follows.

• Hackerrank - algorithms
• Hackerrank - data structures
• ACM Contest Problems

Study Guide

In this section we plan to develop a study guide for use in CS 151. Check back for a laundry list of concepts, keywords, builtin packages, etc. that you should know.
