WGU Foundations of Programming (Python) - E010 JIV1 Sample Questions (Q45-Q50):

NEW QUESTION # 45
Which keyword moves a loop immediately to its subsequent iteration?

Answer: B

Explanation:
The Python keyword continue is used inside a loop to skip the rest of the current iteration and move immediately to the next iteration.
Example:
for number in range(5):
if number == 2:
continue
print(number)
Output:
0
1
3
4
When number is 2, the continue statement skips print(number) for that iteration and moves to the next loop cycle.
The official Python documentation states that the continue statement continues with the next iteration of the loop.
Therefore, the correct answer is C. continue.


NEW QUESTION # 46
Write a complete function calculate_average(grades) that takes a list of grades and returns the average as a float.
For example, calculate_average([85, 92, 78]) should return 85.0.
def calculate_average(grades):
# TODO: Calculate and return the average grade as a float
pass

Answer:

Explanation:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The function receives one parameter named grades, which is a list of numbers.
Step 2: Use sum(grades) to add all the grades together.
Step 3: Use len(grades) to count how many grades are in the list.
Step 4: Divide the total by the number of grades.
Correct code:
def calculate_average(grades):
return sum(grades) / len(grades)
Example:
print(calculate_average([85, 92, 78]))
Output:
85.0


NEW QUESTION # 47
What happens when the command python is entered in a terminal without a filename?

Answer: B

Explanation:
When the command python is entered in a terminal without a filename, Python starts aninteractive Python session, also called interactive mode.
In interactive mode, Python displays the primary prompt:
> > >
The user can then type Python statements directly, such as:
> > > 2 + 3
5
The official Python documentation explains that when commands are read from a terminal, the interpreter is in interactive mode and prompts for the next command.
Python does not automatically run the most recent file, open a file browser, or necessarily display an error when started this way.
Therefore, the correct answer isC. An interactive Python session starts.


NEW QUESTION # 48
What happens when theRunbutton is clicked in a Python development environment?

Answer: D

Explanation:
In a Python development environment, clicking theRunbutton generally executes the currently open Python script or selected code.
For example, if the current script contains:
print( " Hello, Python! " )
clickingRunexecutes the script and displays the output:
Hello, Python!
In Python's IDLE environment, theRun Modulecommand runs the current module. The Python documentation describes IDLE as Python's editor and shell and includes a Run menu for running Python code.
The Run button does not simply open a file browser, save the file without execution, or convert Python code into another programming language.
Therefore, the correct answer isB. The currently open Python script is executed.


NEW QUESTION # 49
How can the first four characters be extracted from the string ' computer ' ?

Answer: A

Explanation:
Python strings are sequences, and sequence values can be accessed using indexing and slicing.
The first character in a Python string has index 0. To extract the first four characters from ' computer ' , the slice should start at index 0 and stop at index 4.
Example:
' computer ' [0:4]
Result:
' comp '
In Python slicing, the start index is included, but the stop index is excluded. So [0:4] includes characters at indexes 0, 1, 2, and 3.
The official Python documentation explains that slicing with a[start:stop] selects items from the start index up to, but not including, the stop index.
Therefore, the correct answer is A. ' computer ' [0:4].
