Python Debugging and Reading Quiz

In this homework, you're going to write code for a challenge problem and answer some reading comprehension questions.

You will practice these programming concepts we've covered in class:

• Type conversion
• Escape characters and string formatting
• Debugging techniques
• Variable scope

---

Deliverables

Part of this homework will be code challenges and part will be reading with comprehension questions.

For the reading quiz, make a text file called answers.txt and use it to compile your answers to the numbered questions.

For each of the code challenges listed below, you will create a new .py file and write code to solve the problem. For example, you would create problem1.py with your solution code to the first problem. Run the file from the command line to check your work.

Reminder: On your laptop, you can run the file from your command line with the following:

python problem1.py

Hint: Make sure you are printing something out with the print statement. Otherwise, you won't see any output from running your program!

Requirements:

By the end of this, you should have:

• One .py file for the code challenge.
• One text file with answers to the five reading comprehension questions.

Code Challenge

Problem 1: We're in a Good Place!

Skill you're practicing: Debugging techniques and variable scope.

Jason is a huge Jacksonville Jaguars fan. The team isn't doing great now, but he has faith: "All we need is a defense, and an offense, and some rule changes!"

Starter Code

offense = False
defense = False
rule_changes = False

def get_offense():
  offense = True

def get_defense():
  defense = True

  def get_rule_changes():
    rule_changes = True

  if offense and defense:
    get_rule_changes()

get_offense()
get_defense()

print("How are the Jags doing?\n")
print("We have offense:", offense)
print("We have defense:", defense)
print("We have some rule changes:", rule_changes)

if offense and defense and rule_changes:
  print("We're going to the Super Bowl!")
else:
  print("I can't predict the future, but no, the Jaguars will never win the Super Bowl.")

Expected Output

How are the Jags doing?

We have offense: True
We have defense: True
We have some rule changes: True
We're going to the Super Bowl!

Actual Output

How are the Jags doing?

We have offense: False
We have defense: False
We have some rule changes: False
I can't predict the future, but no, the Jaguars will never win the Super Bowl.

Hint: Include a bunch of print statements everywhere to print out the values of the variables at various times. For example, inside get_offense(), put a print statement like print('offense is', offense).
