WGU Foundations of Programming (Python) - E010 JIV1 Sample Questions (Q15-Q20):

NEW QUESTION # 15
A program uses this while loop to count down:
count = 5
while count > 0:
print(count)
Which issue is preventing the loop from working correctly?

Answer: A

Explanation:
The loop condition is:
while count > 0:
At the start, count is 5, so the condition is true. The program prints the value of count.
However, inside the loop, the value of count is never changed. That means count always stays 5, so the condition count > 0 is always true. As a result, the loop runs forever.
A corrected version would be:
count = 5
while count > 0:
print(count)
count = count - 1
This decreases count by 1 during each loop iteration. Eventually, count becomes 0, and the condition count >
0 becomes false.
Therefore, the correct answer isB. It runs infinitely because count is never modified.


NEW QUESTION # 16
A dictionary prices = { ' apple ' : 1.50, ' banana ' : 0.75, ' orange ' : 2.00} needs to have all values increased by
0.25. Which code correctly accomplishes this task?

Answer: A

Explanation:
In Python, iterating directly over a dictionary gives itskeys. In this dictionary, the keys are:
' apple '
' banana '
' orange '
To update each price, the program can loop through each key and use that key to access and change the corresponding value.
Correct code:
prices = { ' apple ' : 1.50, ' banana ' : 0.75, ' orange ' : 2.00}
for item in prices:
prices[item] = prices[ item] + 0.25
print(prices)
Output:
{ ' apple ' : 1.75, ' banana ' : 1.0, ' orange ' : 2.25}
Option B is incorrect because value actually receives each dictionary key, not each dictionary value. Also, assigning to value would not update the dictionary.
Option C is incorrect because item is not defined, and the loop structure is invalid for this task.


NEW QUESTION # 17
Which action allows a Python script located in a different folder to be executed in the terminal?

Answer: B

Explanation:
To run a Python script from the terminal, the terminal should be in the correct directory, or the full file path should be provided.
The cd command is commonly used to change directories before running the script.
Example:
cd Documents
python my_script.py
Python's documentation explains that Python can execute a script when the interpreter is called with a filename argument.
Therefore, the correct answer isC. Use the cd command to navigate to the script ' s directory.


NEW QUESTION # 18
Which index position is returned when the string method .find( ' python ' ) is applied to the string ' learning python programming ' ?

Answer: A

Explanation:
The .find() method returns the lowest index where the searched substring is found.
Example:
" learning python programming " .find( " python " )
Output:
9
Indexing starts at 0 in Python. In the string ' learning python programming ' , the word ' python ' begins at index 9. Python's built-in types documentation describes str.find() as returning the lowest index where the substring is found.
Therefore, the correct answer isB. 9.


NEW QUESTION # 19
Which Python data structure allows duplicate values and supports methods like append() and remove()?

Answer: D

Explanation:
A list is a Python data structure that can store multiple values. Lists can contain duplicate values, and they support methods such as append() and remove().
Example:
fruits = [ " apple " , " banana " , " apple " ]
fruits.append( " orange " )
fruits.remove( " banana " )
print(fruits)
Output:
[ ' apple ' , ' apple ' , ' orange ' ]
The value " apple " appears more than once, showing that lists allow duplicates.
The official Python documentation lists list.append() as a method that adds an item to the end of a list and list.
remove() as a method that removes the first matching value from a list.
Therefore, the correct answer is C. List.
