Let's start experimenting with some Python code! This is a set of exercises for MSCH-C220; they should give you the tools to help build your first game.
This exercise assumes that you have already installed Python, GitHub Desktop, and VS Code, and that you have already created a GitHub account. If that is not the case, please refer to previous exercises.
This repository contains several files that you will need to alter to complete the assignment. Fork this repository (instructions below) and edit the files. Commit and push the changes back to GitHub and turn in the URL to your repository on Canvas.
Comments in Python are marked by a # sign (for single-line comments) or three matching quotation marks (''' or """) if a comment requires more than one line. They should also appear in a different color in VS Code. The Python Interpreter ignores comments, so you can safely include any information you want there.
If you wish your exercise to be graded, please edit the LICENSE file (add the current year and your name).
Edit README.md to answer the following questions:
- Open main01.py. Before running it, what do you expect this program to do?
- Now right click on the main1.py window and select “Run Python File in Terminal”. Click in the bottom panel, and answer the question. Describe what happened.
- What do you think the program did with what you typed in answer to the question?
#This code will just say "Greetings!" and then ask for the user to type a response to the question "What is my favorite color?" #It did that. And then ended. #It didn't store it as a variable, but I assume it does store the input somewhere
- Open main02.py. Before running it, describe how this is different than main01.py.
- What do you think the color = input() will do?
- Run the program in the terminal and answer the question. Did the program do what you expected?
#This time the input is stored as a variable named "color" #color = input() just stores the input as the answer to the question #yes
- Open main03.py. Before running it, describe how this is different than main02.py.
- What is happening on lines 9–12?
- Why are lines 10 and 12 indented?
- Run the program and answer the question. What happens if you don’t capitalize Red?
- What does this tell you about "color"?
#This time, there is an if/else statement that tells you if you correctly guessed the favorite color #Lines 9-12 determine whether you answered the question with the correct answer or not and tells you #They only happen if the conditions in the statement are met (or not, for the else) #then you are wrong #whatever you input for "color" must be exactly the same as "Red" for it to work
- Open main04.py. Before running it, describe how this is different than main03.py.
- What problem is this trying to solve?
- Run the program and answer the question. What happens if you use some other capitalization scheme (i.e., “RED” or “reD“)?
#the capitalization error #It's still wrong
- Open main05.py. What do you expect line 9 to do?
- What problem is it trying to solve?
- Run the program and answer the question. What happens if you add spaces before or after the word (i.e., “ RED “ or “ red”)?
#line 9 should change "color" to all lowercase letters and then compares it to "red" so that capitalization in the input shouldn't matter #the capitalization error #it will not work
- Open main06.py. How is line 9 different than in main05.py?
- What would you guess .strip() is doing?
- Run the program and answer the question. Is there another way of writing “red” that will break this logic?
#line 9 has an additional function added to it #as you said in class, .strip() strips the spaces from the beginning/end of the input #if you put spaces between the letters (i.e. "r e d"), it will not work
- Open main07.py. Before running this program, how do you expect this to be different than main06.py?
- What is happening on line 12?
- Run the program and answer the question.
#There's an extra response for if you type an answer that is closer to the correct one #There's an additional statement with new parameters
- Open main08.py. What is the purpose of line 9?
- Why are lines 10–17 indented?
- Run the program. What would happen if line 10 were moved before line 9 (and no longer indented)?
- Make that change and run the program again. (To end any Python program, you can type ctrl-c)
#it creates a loop that will continue until a condition is met #they are within the loop #it would happen outside of the loop and the user would only be able to input once
- Open main09.py. What is happening on line 13?
- What is the purpose of “count”?
- What is happening on line 22?
- Run the program.
#the variable "count" has 1 added to it #it counts how many times the loop runs #it tells the user how many times the loop ran
- Extra credit: open main10.py. Add a comment to each line describing what it is doing (a comment follows a pound sign [#]).
- Extra credit: open main11.py. What is happening on lines 6-11?
Commit your changes and push them back to the repository.
Instructions for forking this repository:
Log into your account on github.com
Go to the exercise template page on GitHub
There is a button in the top right corner of the page labeled "Fork". Press that now
This will create an independent copy of this repository in your account that you can control and edit
Go to your GitHub home page, and select the new E02a-Control-Structures repository
On that page, you will see a green button labeled "Clone or download". Press that now. You will see a drop down box. Press the "Open in Desktop" button.
This should launch GitHub Desktop. It will ask you for a location (on your computer) where the repository may be cloned (downloaded). Choose a location that will be easy for you to find, and press the blue "Clone" button.
Once GitHub Desktop has cloned (downloaded) the code, it will be responsible for keeping the code on your local computer synchronized with the repository in your GitHub account. Now, open Visual Studio Code, and choose File->Open. Find the folder of the cloned repository and select Open.
In the left (File Explorer) panel, you should see a list of files that comprise this repository
First, edit the file called LICENSE. Replace year and name with the current year and your name. Save this file
Then open README.md. Feel free to remove any extraneous information, and then answer the questions posed in the file. You can add your answers after each question
When the time comes for you to run any of the python files, you can do so by clicking the green arrow in the top right corner of the window or by right-clicking on the code and selecting "Run Python File in Terminal". The results will appear at the bottom. If you don't see "Run Python File in Terminal" in the contextual menu, that is because VS Code doesn't have the Python extension installed. You can do that here: https://marketplace.visualstudio.com/items?itemName=ms-python.python
When you are done editing the files, return to GitHub Desktop. In the left panel, you should see a list of the files that have changed
At the bottom of the leftmost area, you should see a text box labeled "Summary (required)". Add a message that describes what you have done; these messages are typically stated in the active-present tense. For example, "Updates the LICENSE, README.md, and completes the assignment." Push the blue "Commit to master" button
In the top bar of the window, you should see a button that is labeled "Push origin", push that now
Check out your page on GitHub. You should see the changes you made reflected there, Repeat steps 10 through 16 as necessary
When you are satisfied with your efforts, turn in a URL to your repository on Canvas
If you try to push your changes, and you receive a permission error, it is likely that you are trying to edit the BL-MSCH-C220-S20 copy of the repository rather than your own. Make sure you don't skip the step of forking your own copy and cloning that.
The grading criteria will be as follows:
[1 point] Repository contains a description of the project in README.md
1 point will be awarded for answering the questions associated with each of the files
