Important WGU Foundations of Programming Python Exam Questions

Answer: C

Explanation:

A terminal-based Python environment uses atext-based command line interface. In this environment, the user types commands directly into a terminal or command prompt.

For example, a user may start Python by typing:

python

When Python is started from a terminal, the interpreter can run in interactive mode, where it displays prompts such as >>> and waits for the user to enter Python commands. The official Python documentation explains that when commands are read from a terminal, the interpreter is in interactive mode.

A terminal-based environment is not mainly identified by graphical user interface elements, internet connectivity, or automatic file saving.

Therefore, the correct answer isC. Text-based command line interface.

Answer: C

Explanation:

A list is a Python data structure that can store multiple values. Lists can contain duplicate values, and they support methods such as append() and remove().

Example:

fruits = ['apple', 'banana', 'apple']

fruits.append('orange')

fruits.remove('banana')

print(fruits)

Output:

['apple', 'apple', 'orange']

The value 'apple' appears more than once, showing that lists allow duplicates.

The official Python documentation lists list.append() as a method that adds an item to the end of a list and list.remove() as a method that removes the first matching value from a list.

Therefore, the correct answer is C. List.

Answer: A

Explanation:

==========

Step 1: The function receives the original price and the discount_percent.

Step 2: Convert the discount percentage into a decimal by dividing by 100.

Step 3: Subtract the discount from 1 to find the remaining price percentage.

Step 4: Multiply the original price by the remaining percentage.

Correct code:

def calculate_discount(price, discount_percent):

return price * (1 - discount_percent / 100)

Example:

print(calculate_discount(75, 20))

Output:

60.0

Answer: A

Explanation:

==========

Step 1: In Python, the code inside a function must be indented.

Step 2: The return statement belongs inside the function body.

Step 3: Add indentation before the return statement.

Correct code:

def greet(name):

return 'Hello ' + name

Example:

print(greet('Alice'))

Output:

Hello Alice

Answer: A

Explanation:

Step 1: The function receives two parameters: bill and tip_percent.

Step 2: Convert the percentage into a decimal by dividing tip_percent by 100.

Step 3: Multiply the bill amount by that decimal value.

Correct code:

def calculate_tip(bill, tip_percent):

return bill * tip_percent / 100

Example:

print(calculate_tip(50, 20))

Output:

10.0
