Answer:
Here is the Python program which has a function sum_scores:
def sum_scores(score1, score2, score3, score4):
sum = score1 + score2 + score3 + score4
print(sum)
sum_scores(14,7,3,0)
Explanation:
- Method sum_scores takes four arguments, score1, score2, score3, score4.
- The sum variable adds these four scores and stores the value of their addition.
- Lastly print statement is used to print the value stored in sum variable which is the value obtained by adding the four scores.
- Last statement calls the sum_scores method and passes four values to it which are 14,7,3,0
- The output of the above program is:
- 24
- If you want to use return statement instead of print statement you can replace print(sum) with return sum. But in order to display the sum of the scores you can replace sum_scores(14,7,3,0) with print(sum_scores(14,7,3,0))
- The program along with the output is attached as a screenshot.
Answer:
The advantage for the above condition is as follows:-
Explanation:
- If a user creates a defined constant variable and assigns a value on its and then uses that variable instead of the value, then it will a great advantage.
- It is because when there is a needs to change the value of that variable, then it can be done when the user changes the value in one place. There is no needs to change the vale in multiple places.
- But if there is a value in multiple places instead of a variable and there is no constant variable, then the user needs to change the value in multiple places.
Answer:
1)
officeAC = new AirConditioner();
officeAC.turnOn();
2)
officeAC = new AirConditioner();
officeAC.turnOn();
officeAC.setTemp(69);
Explanation:
1)
In the first statement a new object of the class AirConditioner whose reference is assigned to the officeAC. new is a keyword which creates an object of the class.
Next statement uses the method turnOn(). Reference to the new object officeAC is used to invoke this method turnOn().
2) The first two statements works the same as in 1)
The last statement invokes a method setTemp() using the reference variable and passes the value 69 to this method to set the desired temperature.
Answer:
Normalization
Explanation:
Converting a poorly-structured table and optimizing its database structure in order to reduce redundancy in relations can be referred to as database normalization. If the data is not redundant means that data inconsistencies and errors like deletion and insertion will get reduced or eliminated significantly.
