WGU Foundations of Programming (Python) - E010 JIV1 Sample Questions (Q37-Q42):

NEW QUESTION # 37
Which data type is the value 3.14 in Python?

Answer: D

Explanation:
The value 3.14 is afloatbecause it contains a decimal point.
Example:
type(3.14)
This returns:
< class ' float ' >
Python's built-in numeric types include integers and floating-point numbers. A value with a decimal part, such as 3.14, is treated as a floating-point number.
Therefore, the correct answer isB. Float.


NEW QUESTION # 38
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 # 39
Which loop structure processes every individual item in a list called grades?

Answer: B

Explanation:
The loop:
for grade in grades:
print(grade)
processes every individual item in the list grades.
The variable grade represents the current item being processed. Python's documentation explains that a for statement iterates over the items of a sequence in order.
Therefore, the correct answer isB. for grade in grades:.


NEW QUESTION # 40
Write a complete function reverse_string(text) that takes a string and returns it reversed.
For example, reverse_string( " hello " ) should return " olleh " .
def reverse_string(text):
# TODO: Return the reversed string
pass

Answer:

Explanation:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The function receives one string parameter named text.
Step 2: Python slicing can be used to reverse a string.
Step 3: The slice [::-1] means start at the end of the string and move backward by one character at a time.
Step 4: Return text[::-1].
Correct code:
def reverse_string(text):
return text[::-1]
Example:
print(reverse_string( " hello " ))
Output:
olleh


NEW QUESTION # 41
Fix the off-by-one error in this function that should return the first 3 characters of a string.
def first_three(text):
return text[0:2]

Answer:

Explanation:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: Python string slicing uses this format:
text[start:stop]
Step 2: The start index is included.
Step 3: The stop index is excluded.
Step 4: To return the first 3 characters, start at index 0 and stop at index 3.
Correct code:
def first_three(text):
return text[0:3]
Simplified correct code:
def first_three(text):
return text[:3]
Example:
print(first_three( " Python " ))
Output:
Pyt
