NEW QUESTION # 17
Which components are required in every Python while loop?
Answer: D
Explanation:
A Python while loop needs a condition and an indented code block.
Example:
count = 1
while count < = 3:
print(count)
count += 1
The condition is count < = 3. The indented block contains the code that runs while the condition is true.
Python's compound statement documentation includes while as a control-flow statement.
Therefore, the correct answer isA. A condition and an indented code block.
NEW QUESTION # 18
What advantage does an integrated terminal provide compared to using a separate terminal application?
Answer: D
Explanation:
An integrated terminal is built into a development environment or code editor. Its main advantage is that the developer can write code and run terminal commands in the same application.
This avoids switching back and forth between a separate terminal window and the code editor.
Therefore, the correct answer isC. Eliminates need to switch between applications.
NEW QUESTION # 19
Fix the logic error in this function that should return the larger of two numbers.
def find_maximum(a, b):
if a < b:
return a
else:
return b
Answer:
Explanation:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The function should return the larger number.
Step 2: The condition a < b means b is larger than a.
Step 3: In the original code, when a < b is true, it incorrectly returns a.
Step 4: The return values need to be corrected.
Correct code:
def find_maximum(a, b):
if a < b:
return b
else:
return a
Alternative correct code:
def find_maximum(a, b):
if a > b:
return a
else:
return b
Example:
print(find_maximum(10, 20))
print(find_maximum(30, 15))
Output:
20
30
NEW QUESTION # 20
Which symbol begins a single-line comment in Python?
Answer: A
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 # 21
A program needs to update all values in a list by adding 5 to each number. Which for loop structure accomplishes this task?
Answer: B
Explanation:
To update the actual values inside a list, the program must update each value by itsindex.
The correct code is:
for i in range(len(numbers)):
numbers[i] = numbers[i] + 5
Here, range(len(numbers)) produces valid index positions for the list. The variable i is used to access and update each list element.
Example:
numbers = [10, 20, 30]
for i in range(len(numbers)):
numbers[i] = numbers[i] + 5
print(numbers)
Output:
[15, 25, 35]
Option A does not correctly update the original list:
for number in numbers:
number = number + 5
This changes only the temporary loop variable number, not the actual elements stored inside the list.
Therefore, the correct answer isB.
