To quit, a user types 'q'. To continue, a user types any other key. Which expression evaluates to true if a user should continue

Computers and Technology
1 answer:
devlian [24]2 years ago

Answer:

!(key == 'q')

Explanation:

Based on the description, the coded expression that would equate to this would be

!(key == 'q')

This piece of code basically states that "if key pressed is not equal to q", this is because the ! symbol represents "not" in programming. Meaning that whatever value the comparison outputs, it is swapped for the opposite. In this case, the user would press anything other than 'q' to continue, this would make the expression output False, but the ! operator makes it output True instead.

yaroslaw [1]

Answer:

<em>The program doesn't use comments; See explanation section for detailed line by line explanation</em>

<em>Program starts here</em>

def lettergrade(subject,score):

     print(subject+": "+str(score))

     if score >= 90 and score <= 100:

           print("Letter Grade: A")

     elif score >= 80 and score <= 89:

           print("Letter Grade: B")

     elif score >= 70 and score <= 79:

           print("Letter Grade: C")

     elif score >= 60 and score <= 69:

           print("Letter Grade: D")

     elif score >= 0 and score <= 59:

           print("Letter Grade: F")

     else:

           print("Invalid Score")

maths = int(input("Maths Score: "))

english = int(input("English Score: "))

pe = int(input("PE Score: "))

science = int(input("Science Score: "))

arts = int(input("Arts Score: "))

lettergrade("Maths Class: ",maths)

lettergrade("English Class: ",english)

lettergrade("PE Class: ",pe)

lettergrade("Science Class: ",science)

lettergrade("Arts Class: ",arts)

Explanation:

The program makes the following assumptions:

Scores between 90–100 has letter grade A

Scores between 80–89 has letter grade B

Scores between 70–79 has letter grade C

Scores between 60–69 has letter grade D

Scores between 0–69 has letter grade E

<em>Line by Line explanation</em>

This line defines the lettergrade functions; with two parameters (One for subject or class and the other for the score)

def lettergrade(subject,score):

This line prints the the score obtained by the student in a class (e.g. Maths Class)

     print(subject+": "+str(score))

The italicized determines the letter grade using if conditional statement

<em>This checks if score is between 90 and 100 (inclusive); if yes, letter grade A is printed</em>

<em>      if score >= 90 and score <= 100:</em>

<em>            print("Letter Grade: A")</em>

<em />

<em>This checks if score is between 80 and 89 (inclusive); if yes, letter grade B is printed</em>

<em>      elif score >= 80 and score <= 89:</em>

<em>            print("Letter Grade: B")</em>

<em />

<em>This checks if score is between 70 and 79 (inclusive); if yes, letter grade C is printed</em>

<em>      elif score >= 70 and score <= 79:</em>

<em>            print("Letter Grade: C")</em>

<em />

<em>This checks if score is between 60 and 69 (inclusive); if yes, letter grade D is printed</em>

<em>      elif score >= 60 and score <= 69:</em>

<em>            print("Letter Grade: D")</em>

<em />

<em>This checks if score is between 0 and 59 (inclusive); if yes, letter grade F is printed</em>

<em>      elif score >= 0 and score <= 59:</em>

<em>            print("Letter Grade: F")</em>

<em />

<em>If input score is less than 0 or greater than 100, "Invalid Score" is printed</em>

<em>      else:</em>

<em>            print("Invalid Score")</em>

This line prompts the user for score in Maths class

maths = int(input("Maths Score: "))

This line prompts the user for score in English class

english = int(input("English Score: "))

This line prompts the user for score in PE class

pe = int(input("PE Score: "))

This line prompts the user for score in Science class

science = int(input("Science Score: "))

This line prompts the user for score in Arts class

arts = int(input("Arts Score: "))

The next five statements is used to call the letter grade function for each class

lettergrade("Maths Class: ",maths)

lettergrade("English Class: ",english)

lettergrade("PE Class: ",pe)

lettergrade("Science Class: ",science)

lettergrade("Arts Class: ",arts)
