Final

What to bring¶

• Yourself.
• Your UW ID card.
• A pen or pencil and eraser.
• Water.
• A 1-page cheatsheet (8.5” x 11”, can be double sided)
  • Note: we will provide a reference sheet that includes some documentation that you won’t have to memorize or include on your own cheatsheet.
  • The reference sheet may change between now and the exam date.

Where to sit¶

Seating in the room will be done by section. Please refer to the given seating chart for where to sit.

Format¶

This is a hand-written test, meaning NO ELECTRONIC DEVICES of any kind allowed. Any math on the exam will be limited to simple arithmetic; we’re assessing for Python and programming, not for math!

Question types may include some of the following. Note: this is not an exhaustive list, nor will all of these formats appear. This list is meant to give you an idea of what might possibly appear on the exam.

• Given a program, function, or code snippet and possible inputs, what is the output?
• What is the value of variables X, Y, Z on line N?
• Fill in the code: Replace the blanks on line N with an appropriate statement or expression
• Evaluate expressions
• Write a function that takes … and returns …

Topics¶

Every topic covered in the quarter is fair game for appearing on the exam.

The short list of topics are:

• Variables, Statements, Expressions
• For loops, range, nested loops
• If statements and conditionals
• Functions, function arguments, and return statements
• Lists and nested lists
• File input/output (I/O)
• Dictionaries
• Sets
• Graphs
• Sorting
• Testing
• Classes
• List comprehensions

Practice¶

These past quarters’ finals may be helpful in practice and studying:

• 23wi Final (and its answer key)
• 23sp Final (and its answer key)
• 23su Final (and its answer key)

• 15sp Final (and its answer key)
• 16wi Final (and its answer key)
• 17wi Final (and its answer key)
• 18sp Final (and its answer key)

Some notable differences (this list may be updated over time):

• print statements are missing parentheses. They are now required.
• Division prior to 23wi worked differently: with the current version of Python, division by default produces floats. For example 3 / 5 evaluates to 0.6. To do “truncated” division, producing an int, use a double slash: 3 // 5 evaluates to 0.
• Any “draw the environment” questions will not be on this quarter’s exam, and you can skip or ignore those questions from past exams.
• Many of these refer to “stack frames.” These are similar to the “Frames” in Python Tutor, but since we haven’t explicitly covered this term, we won’t talk about it in the final exam.
• These exams are slightly longer than what you should expect this quarter.
• All exams prior to 2020 used an older version of Python. You should assume that everything this quarter is with Python 3.7. (If this means nothing to you, don’t worry about it!)
