	To Fulfill a Course Requirement
	To Get a Good Grade
	other

Select all of the resources that you are aware of or have used to help learn how to program.

	Google
	Online coding courses
	Stack Overflow
	Friends that know how to program

2) Class Info Assessment

(did you read the course info page?)

Which of the following count towards your grade?

	problem sets
	mandatory exercises
	optional exercises on MITx
	exams
	lecture attendance and participation
	recitation attendance and participation

When are problem sets due?

	every Monday
	every Wednesday
	depends on the pset, check the calendar

When are mandatory finger exercises due?

	generally available with the pset, and due with the pset
	generally available with a lecture, and due by the beginning of next lecture
	no deadline per exercise, but must do them all by the end of the course

Microquizzes are in the last 30-45 minutes of specific lectures outlined in the calendar. What happens if you cannot make it to a microquiz?

	Email S^3 and post to the forum to schedule a conflict microquiz
	Conflict microquizzes are not given but the lowest quiz grade is dropped

You are working with a friend on the problem set. Your friend tells you to use a specific kind of loop to solve a part. Is this a collaboration violation?

	Yes for you and the friend
	Yes only for the friend
	Yes only for you
	no

You are stuck debugging the problem set. Your friend already finished but they can't stay to help you anymore, so they email you the code. You look over the part you are stuck but write up your own code. Is this a collaboration violation?

	Yes for you and the friend
	Yes only for the friend
	Yes only for you
	no

3) Getting Started with Python

The rest of this problem set is about setting up your Python environment, writing a simple Python program, and submitting it on our website. Your submission will not be graded, but subsequent problem sets will rely on this procedure.

3.1) Collaboration

Please read carefully the Collaboration Policy in the course info page. For this pset, you may consult anyone to help set up your Python environment, but you should individually write and submit your Python program.

3.2) Setting up Python

Follow the Installing Python instructions under the About tab in the top menu. These will guide you through installing Python, the VS Code editor, and some Python packages we'll need in the course. If you choose not to use the VS Code setup outlined in those instructions, then you are responsible for providing your own Python environment. We use Python 3.9+ in this class, and require the following Python packages:

• matplotlib
• numpy
• pandas
• scikit-learn
• seaborn

3.3) Your First Program

The goal is to exercise using some simple elements of Python, including: the ability to print out results (using the print operation), the ability to read input from a user at the console (using the input function), and the ability to store values in variables, so that the program can access those values as needed.

In the file named ps0.py, write a program that does the following in order:

1. Ask the user to enter a number x.
2. Ask the user to enter a number y.
3. Print the value of x raised to the power y.
4. Print all the digits of x followed by all the digits of y, with no spaces.

An example run of the program is shown below. The numbers printed after :   on a line are instances of a user's input. The rest should be printed by your program.

Enter number x: 78
Enter number y: 9
x to the power of y is 106868920913284608
x smushed with y is 789

When you finish installing your programming environment, you're all set. There is nothing to hand in for this problem set!
