WGU Foundations of Programming Python Exam Questions

To run a Python script from a text editor using the terminal on Windows, the file should first be saved with the .py extension. Then, the terminal is opened, and the script is executed using the Python command followed by the filename.

Example:

python filename.py

The official Python documentation explains that when the interpreter is called with a filename argument, it reads and executes the script from that file. On Windows, the python command can be used from a terminal after Python is installed and configured correctly.

Therefore, the correct answer is A. Save file > open terminal > type python filename.py.

In a Python for loop, the in keyword is followed by an iterable object, such as a list, string, tuple, dictionary, set, or range() object.

Example:

for name in ['Alice', 'Bob', 'Carol']:

print(name)

Here, ['Alice', 'Bob', 'Carol'] is the iterable object. Python's documentation explains that a for statement iterates over the items of a sequence or other iterable object.

Therefore, the correct answer isB. An iterable object.

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

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.

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.
