Python can recognise this data: "hello"

Yes
No
Sometimes

Correct Answer

A. Yes

Explanation

Python can recognize the data "hello" because it is a string literal enclosed in quotation marks. In Python, strings are a built-in data type and can be defined using single quotes ('hello') or double quotes ("hello"). The given data is enclosed in double quotes, which is a valid way to define a string in Python. Therefore, Python can recognize and interpret the given data as a string.

Python can recognise this data: 56.97

Yes
No
Sometimes

Correct Answer

A. Yes

Explanation

Python can recognize the data "56.97" because it is a valid floating-point number. In Python, floating-point numbers are represented with a decimal point, allowing for both whole numbers and fractions. The given data follows this format, making it recognizable by Python.

Python can recognise this data: computer

Yes
No
Sometimes

Correct Answer

A. Sometimes

Explanation

Python can sometimes recognize the data "computer" depending on the context and how it is used. Python is a versatile programming language that can handle various types of data, including strings like "computer". However, the recognition of this data may depend on the specific program or code being written in Python. In some cases, Python may not be able to recognize the data if it is not properly formatted or if it is used in a way that is not supported by the language. Therefore, the answer is "Sometimes".

Python can recognise this code: 3 + 6 * 8

Yes
No
Sometimes

Correct Answer

A. Yes

Explanation

Python can recognize and evaluate mathematical expressions using the correct order of operations. In the given code, 3 + 6 * 8, Python will first multiply 6 by 8, resulting in 48, and then add 3 to it, resulting in 51. Therefore, Python can recognize and evaluate this code correctly.

In Python, the _______ statement is used to terminate a loop prematurely.

Correct Answer
break, Break, BREAK

Explanation
The break statement is used to exit a loop (e.g., for loop or while loop) before it has completed all its iterations. When the break statement is encountered within a loop, the loop terminates immediately, and the program execution continues with the next statement after the loop. This can be useful for situations where you want to exit a loop based on a certain condition or when you have found the desired result within the loop.

Python will run this program without errors: print("hello")

True
False

Correct Answer

A. True

Explanation

The given program consists of a single line of code that uses the print() function to display the string "hello". This is a valid Python syntax and will run without any errors. Therefore, the correct answer is True.

Python will run this program without errors: print(765.9908) print("that was a number")

True
False

Correct Answer

A. True

Explanation

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.

The output of this program will be? print("5+7+2")

14
12
5+7+2
Nothing. It will return an error.

Correct Answer

A. 5+7+2

Explanation

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.

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)

Hello Hi, This is a number
HelloHi, This is a number6812
Nothing, it will return an error
Hello Hi, text box2 boxbox box
Hello This is a number Hi, 4 box2 boxbox boxbox-box

Correct Answer

A. Hello Hi, This is a number

Explanation

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.

This program will run without errors: print(x) x = 3 print(x+3)

True
False

Correct Answer

A. False

Explanation

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.

What structure do you use to let the computer make decisions in Python?

Because structure
If statement
Decision structure
Decide statement

Correct Answer

A. If statement

Explanation

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.

What optional part can you add to an if statement?

Who
Else
Then
Nothing

Correct Answer

A. Else

Explanation

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.

Which of these could python run without errors?

X = 5 if x < 10 print("hi")
X = 5 if x < 10: print("hi")
Both
Neither

Correct Answer

A. Neither

Explanation

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.

This program is full of errors. What do you need to change to make it correct?cat_weight = 45 if cat_wieght = 50; print your cat is healthy else: print unhealthy

The variable name has been spelled wrong
Variable names should start with $
If statements end in a colon, not semicolon
Instructions underneath an if and an else should be indented by 4 spaces
Every line ends in a semicolon
Words that python should understand should be "surrounded by quotes".
You have to say what type of data something is when you declare a variable.
Else statements end in a semicolon, not a colon
Print() should always be written with brackets
You should use ==, not = to check if two things are equal
You should always include units when working with numbers in Python

Correct Answer(s)

A. The variable name has been spelled wrong
A. If statements end in a colon, not semicolon
A. Instructions underneath an if and an else should be indented by 4 spaces
A. Words that python should understand should be "surrounded by quotes".
A. Print() should always be written with brackets
A. You should use ==, not = to check if two things are equal

Explanation

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.
