WGU Foundations of Programming (Python) - E010 JIV1 Sample Questions (Q43-Q48):

NEW QUESTION # 43
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].


NEW QUESTION # 44
What happens when the command python is entered in a terminal without a filename?

Answer: A

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 # 45
Which symbol begins a single-line comment in Python?

Answer: B

Explanation:
In Python, a single-line comment begins with the # symbol.
Example:
# This is a comment
print( " Hello " )
Python ignores the comment when the program runs. The Python documentation identifies # as the symbol used for comments.
Therefore, the correct answer isB. # pound symbol.


NEW QUESTION # 46
Which punctuation mark must appear at the end of an if statement line?

Answer: D

Explanation:
In Python, an if statement line must end with a colon.
Example:
age = 18
if age > = 18:
print( " Adult " )
The colon : tells Python that an indented block of code follows. That indented block contains the statements that should run when the condition is true.
A semicolon, period, or comma is not used to begin the body of an if statement in Python.
Therefore, the correct answer is B. : colon.


NEW QUESTION # 47
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
