Python will run this program without errors: print(765.9908) print("that was a number")
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The given program consists of two print statements. The first print statement prints a floating-point number, 765.9908. Since there are no syntax errors or any other issues in this statement, Python will execute it without any errors. The second print statement prints a string, "that was a number". Again, there are no errors in this statement. Therefore, Python will run this program without any errors, resulting in the correct answer being True.Rate this question:

The output of this program will be? print("5+7+2")
- A.
14
- B.
12
- C.
5+7+2
- D.
Nothing. It will return an error.
Correct Answer
C. 5+7+2Explanation
The output of this program will be "5+7+2". This is because the print statement is printing the exact string "5+7+2" as it is, without evaluating the expression. Therefore, the output will be the string itself, not the result of the addition.Rate this question:

What will the output of this program be? print("Hello") text = "This is a number" print("Hi, " + text) number = 4 print(box + 2) print(box * 2) print(box * box - box)
- A.
Hello Hi, This is a number
- B.
HelloHi, This is a number6812
- C.
Nothing, it will return an error
- D.
Hello Hi, text box2 boxbox box
- E.
Hello This is a number Hi, 4 box2 boxbox boxbox-box
Correct Answer
A. Hello Hi, This is a numberExplanation
The program will output "Hello" and "Hi, This is a number" successfully. However, it will encounter an error at print(box + 2) because the variable box is not defined anywhere in the program. This will stop the program's execution before it can reach the subsequent print statements involving box. Thus, the output will include the first two print statements, followed by an error due to the undefined variable box.Rate this question:

This program will run without errors: print(x) x = 3 print(x+3)
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The program will not run without errors because the variable x is being printed before it is assigned a value. When the print(x) statement is encountered, x has not been defined yet, resulting in an error.Rate this question:

What structure do you use to let the computer make decisions in Python?
- A.
Because structure
- B.
If statement
- C.
Decision structure
- D.
Decide statement
Correct Answer
B. If statementExplanation
In Python, the if statement is used to let the computer make decisions. It allows the program to execute a certain block of code only if a specific condition is true. The if statement evaluates the condition and if it is true, the code inside the if block is executed. Otherwise, it is skipped. This decision structure is fundamental in programming as it allows for different actions to be taken based on different conditions.Rate this question:

What optional part can you add to an if statement?
- A.
Who
- B.
Else
- C.
Then
- D.
Nothing
Correct Answer
B. ElseExplanation
An optional part that can be added to an if statement is the "else" clause. This allows for an alternative block of code to be executed if the condition in the if statement evaluates to false. The code within the else block will be executed when the condition is not met, providing an alternative path of execution.Rate this question:

Which of these could python run without errors?
- A.
X = 5 if x < 10 print("hi")
- B.
X = 5 if x < 10: print("hi")
- C.
Both
- D.
Neither
Correct Answer
D. NeitherExplanation
The correct syntax in Python for using an "if" statement with a one-liner is to include a colon after the condition. Therefore, the correct way to write this statement is:
x = 5 if x < 10: print("hi")
Therefore, the correct answer is neither.Rate this question:

C. If statements end in a colon, not semicolon
D. Instructions underneath an if and an else should be indented by 4 spaces
F. Words that python should understand should be "surrounded by quotes".
I. Print() should always be written with brackets
J. You should use ==, not = to check if two things are equalExplanation
The correct answer is: The variable name has been spelled wrong. You should use ==, not = to check if two things are equal. If statements end in a colon, not semicolon. print() should always be written with brackets. Words that python should understand should be "surrounded by quotes". Instructions underneath an if and an else should be indented by 4 spaces.
The given program contains multiple errors. First, the variable name "cat_wieght" has been spelled wrong, it should be "cat_weight". Second, the equality check in the if statement should use == instead of =. Third, if statements in Python end with a colon, not a semicolon. Fourth, the print() function should always be written with brackets. Fifth, words that Python should understand, like "healthy" and "unhealthy", should be surrounded by quotes. Lastly, the instructions underneath the if and else statements should be indented by 4 spaces to indicate that they are part of the respective blocks.Rate this question:
