Information about a computer file, not the actual data that is contained in the file, is called _____

A proper divisor of a positive integer $n$ is a positive integer $d < n$ such that $d$ divides $n$ evenly, or alternatively i

juin [17]

Answer:

The program written in Python is as follows:

See Explanation section for line by line explanation

for n in range(100,1000):

isum = 0

for d in range(1,n):

if n%d == 0:

isum += d

if isum == n * 2:

print(n)

Explanation:

The program only considers 3 digit numbers. hence the range of n is from 100 to 999

for n in range(100,1000):

This line initializes sum to 0

isum = 0

This line is an iteration that stands as the divisor

for d in range(1,n):

This line checks if a number, d can evenly divide n

if n%d == 0:

If yes, the sum is updated

isum += d

This line checks if the current number n is a double-perfect number

if isum == n * 2:

If yes, n is printed

print(n)

When the program is run, the displayed output is 120 and 672

Using Python I need to Prompt the user to enter in a numerical score for a Math Class. The numerical score should be between 0 a

yaroslaw [1]

Answer:

The program doesn't use comments; See explanation section for detailed line by line explanation

Program starts here

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

Line by Line explanation

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

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

if score >= 90 and score <= 100:

print("Letter Grade: A")

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

elif score >= 80 and score <= 89:

print("Letter Grade: B")

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

elif score >= 70 and score <= 79:

print("Letter Grade: C")

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

elif score >= 60 and score <= 69:

print("Letter Grade: D")

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

elif score >= 0 and score <= 59:

print("Letter Grade: F")

If input score is less than 0 or greater than 100, "Invalid Score" is printed

else:

print("Invalid Score")

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)

Nuetrik [128]

Object-oriented databases is more flexible and stores data as well as instructions to manipulate the data.

A system known as an object database uses object-oriented programming to represent data in the form of objects. Different from relational databases, which are table-oriented, are object-oriented databases.

The concept of object-oriented programming languages, which is currently popular, is the foundation of the object-oriented data model. Overloading, polymorphism, and inheritance Object-oriented programming fundamentals that have found use in data modelling include object-identity, encapsulation, and information hiding with methods to provide an interface to objects. The rich type system, which includes collection and structured types, is supported by the object-oriented data model as well.

In contrast to relational databases, which can only handle one type of data, object databases can handle multiple data types. Unlike conventional databases like hierarchical, network, or relational, object-oriented databases can handle a variety of data types, including text, numbers, images, voice, and video.

Also, Reusable code, realistic modelling, and increased dependability and flexibility are all provided by object-oriented databases.
