WGU Foundations of Programming Python Exam Questions

==========

Step 1: First, check the password length using len(password).

Step 2: If the password has fewer than 8 characters, return 'Weak' immediately.

Step 3: Create two Boolean variables: has_letter and has_number.

Step 4: Loop through each character in the password.

Step 5: Use .isalpha() to check for letters and .isdigit() to check for numbers.

Step 6: If the password contains both at least one letter and at least one number, return 'Strong'.

Step 7: Otherwise, return 'Weak'.

Correct code:

def password_strength(password):

if len(password) < 8:

return 'Weak'

has_letter = False

has_number = False

for char in password:

if char.isalpha():

has_letter = True

elif char.isdigit():

has_number = True

if has_letter and has_number:

return 'Strong'

else:

return 'Weak'

Example:

print(password_strength('abc123def'))

print(password_strength('abcdefgh'))

print(password_strength('12345678'))

Output:

Strong

Weak

Weak

Step 1: The function receives two parameters: a and b.

Step 2: Compare the two values using an if statement.

Step 3: If a is greater than or equal to b, return a.

Step 4: Otherwise, return b.

Correct code:

def get_max(a, b):

if a >= b:

return a

else:

return b

Simplified correct code:

def get_max(a, b):

return max(a, b)

Example:

print(get_max(10, 20))

print(get_max(30, 15))

print(get_max(5, 5))

Output:

20

30

5

Step 1: The function receives one parameter named grades, which is a list of numbers.

Step 2: Use sum(grades) to add all the grades together.

Step 3: Use len(grades) to count how many grades are in the list.

Step 4: Divide the total by the number of grades.

Correct code:

def calculate_average(grades):

return sum(grades) / len(grades)

Example:

print(calculate_average([85, 92, 78]))

Output:

85.0

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.
