WGU Foundations of Programming (Python) - E010 JIV1 Sample Questions (Q60-Q65):

NEW QUESTION # 60
Which Python data structure automatically prevents duplicate values from being stored?

Answer: D

Explanation:
Asetstores only unique elements. If duplicate values are added, Python keeps only one copy.
Example:
numbers = {1, 2, 2, 3}
print(numbers)
Output:
{1, 2, 3}
Python's data structures documentation describes sets as collections with no duplicate elements.
Therefore, the correct answer isD. Set.


NEW QUESTION # 61
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: C

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 # 62
Which Python data structure cannot be modified after creation?

Answer: A

Explanation:
Atupleis immutable, which means it cannot be changed after it is created.
Example:
coordinates = (10, 20)
After this tuple is created, its elements cannot be modified directly. Python's data model documentation explains that tuples are immutable, while lists and dictionaries are mutable.
Therefore, the correct answer isC. Tuple.


NEW QUESTION # 63
Fix the indexing error in this function that should return the last character of a string.
def get_last_character(text):
return text[len(text)]

Answer:

Explanation:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: Python string indexing starts at 0.
Step 2: The last valid index of a string is len(text) - 1, not len(text).
Step 3: Python also allows negative indexing, where -1 means the last character.
Step 4: Replace text[len(text)] with text[-1] .
Correct code:
def get_last_character(text):
return text[-1]
Example:
print(get_last_character( " Python " ))
Output:
n


NEW QUESTION # 64
Complete the function calculate_tip(bill, tip_percent) that calculates and returns the tip amount based on the bill and tip percentage.
For example, calculate_tip(50, 20) should return 10.0.
def calculate_tip(bill, tip_percent):
# TODO: Calculate and return the tip amount
pass

Answer:

Explanation:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The function receives two parameters: bill and tip_percent.
Step 2: Convert the percentage into a decimal by dividing tip_percent by 100.
Step 3: Multiply the bill amount by that decimal value.
Correct code:
def calculate_tip(bill, tip_percent):
return bill * tip_percent / 100
Example:
print(calculate_tip(50, 20))
Output:
10.0
