WGU Foundations of Programming (Python) - E010 JIV1 Foundations of Programming Python Exam Questions

Answer : A

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.

Answer : B

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.

Answer : B

Jupyter Notebook works as acell-based interactive coding platform. A notebook is made up of cells, and code can be written and executed inside those cells.

For example, a code cell may contain:

x = 10

print(x)

When the cell is run, the output appears directly below the cell.

The Jupyter Notebook documentation explains that notebooks consist of a sequence of cells, and the contents of a cell can be executed using keyboard shortcuts or the toolbar button.

Jupyter Notebook is not simply a command-line terminal replacement, not limited to static text editing, and not mainly a framework for compiling Python into standalone applications.

Therefore, the correct answer isB. Cell-based interactive coding platform.

Answer : A

The correct function uses the list method append() to add new_number to the end of numeric_list.

Correct code:

def add_item(numeric_list, new_number):

numeric_list.append(new_number)

return numeric_list

Example:

add_item([1, 2, 3], 4)

Result:

[1, 2, 3, 4]

Python's data structures documentation explains that list.append(x) adds an item to the end of the list.

Therefore, the correct answer isA.

Answer : C

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.

Answer : A

==========

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

Answer : C

In Python, comparison expressions such as 5 > 3 evaluate to aBooleanvalue.

The expression:

5 > 3

checks whether 5 is greater than 3. Since this statement is true, Python returns:

True

True and False are Boolean values in Python.

Therefore, the correct answer isC. Boolean.
