Answer the following question TRUE or False
1. The if statement evaluates the test expression inside the parenthesis ().
If the test expression is evaluated to false, statement inside the body of it are not executed.
2. The if statement evaluates the test expression inside the parenthesis ().
If the test expression is evaluated to true, statement inside the body of it are executed.
3. the “if-else” is statement is an extended version of “if”
What does the 'and' Boolean operator do?
a. It compares two conditions. Only if both are True is the result True
b. It compares two conditions. If at least one is True, the result is True.
c. It flips the value of a condition from True to False or False to True
d. It compares two conditions. If one but not both of the conditions is True, the result is True
A condition in an if-statement can evaluate to what possible conditions?
a. 0, 1 and 2
b. any number of values
c. either True or False

- Scenario As you surely know, due to some astronomical reasons, years may be leap or common. The former are 366 days long, while the latter are 365 days long. Since the introduction of the Gregorian calendar (in 1582), the following rule is used to determine the kind of year: if the year number isn't divisible by four, it's a common year, otherwise, if the year number isn't divisible by 100, it's a leap year. otherwise, if the year number isn't divisible by 400, it's a common year. otherwise, it's a leap year. none of the above year int(input("enter the year")) if (year%4 1-0) and (year%400 -0) or (year % 1000): print (year is common year") else: print(year, is leap year") year= int(input ("enter the year")) if (years !-0) or (year480 1-0) and (year % 1001-0): print(year is common year") else: print(year, "is leap year") D year= int(input("enter the year"))arrow_forwardBoth while loops and do-while loops are executed as long as a stated boolean condition is true and both while loops and do while loops terminate if the boolean condition is false. What is the only (major, key) difference between the two types of loops. 1. while loops are faster 2. A do-while loop can be rewritten as a for loop, but we cannot rewrite a while loop as a for loop. 3. A do while loop will always execute the loop statements once, but it is possible that a while loop skip all of its loop statements.arrow_forwardThe else in a set of if statements is sometimes called the "catch all"?

- Which of the following statements is true about the use of Boolean expressions? Select one: a. They cannot contain two not operators because they cancel each other out. b. The must contain at least one and operator. c. They can help simplify selection structures. d. The can only be used in single selection statements.arrow_forwarda) In the Hi-Lo game, the player begins with a score of 1000. The player is prompted for the number of points to risk and a second prompt asks the player to choose either High or Low. The player’s choice of either High or Low is compared to a random number between 1 and 13, inclusive. If the number is between 1 and 6 inclusive, then it is considered “low”. A number between 8 and 13 inclusive is “high”. The number 7 is neither high nor low, and the player loses the points at risk. If the player had guessed correctly, the points at risk are doubled and added to the total points. For a wrong choice, the player loses the points at risk. Create a HiLo application based on this specification. Application output should look similar to b) Modify the application to allow the player to continue until there are 0 points left.
