Complete the function add_item(numeric_list, new_number) that takes a list of numbers and a new number, and returns a new list that appends the new number to the end of the list.

For example, add_item([1, 2, 3], 4) should return [1, 2, 3, 4].

def add_item(numeric_list, new_number):

# TODO: Add new_number to the end of the list and return the list

# Example: add_item([1, 2, 3], 4) should return [1, 2, 3, 4]

pass

def add_item(numeric_list, new_number):

numeric_list.append(new_number)

return numeric_list

Complete the function update_grade(grades, student, new_grade) that takes a grades dictionary, a student name, and a new grade, then updates that student's grade and returns the dictionary.

For example, update_grade({"Alice": 85, "Bob": 90}, "Alice", 95) should return {"Alice": 95, "Bob": 90}.

def update_grade(grades, student, new_grade):

# TODO: Update the student's grade and return the dictionary

# Example: update_grade({"Alice": 85, "Bob": 90}, "Alice", 95)

# should return {"Alice": 95, "Bob": 90}

pass

def update_grade(grades, student, new_grade):

grades[student] = new_grade

return grades

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

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

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

for name = ['Alice', 'Bob', 'Carol']

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

Which loop structure processes every individual item in a list called grades?

while len(grades) > 0:

for grade in grades:

for i in range(grades):

while grades[0]

for grade in grades:

A program needs to display only positive, non-zero numbers from a list containing a mixture of integer and decimal values.

Which conditional statement should be placed inside the loop?

if number > 0:

if number != 0:

if number < 0:

if number >= 1

if number > 0:

Complete the function double_number(num) that takes one number parameter and returns double that number.

For example, double_number(5) should return 10.

def double_number(num):

# TODO: Return double the input number

# Example: double_number(5) should return 10

pass

def double_number(num):

return num * 2

Modify the function greet_with_default(name) by adding a default value of "World" to the name parameter so it can be called with or without an argument.

def greet_with_default(name):

# TODO: Add a default value of "World" to the name parameter

return "Hello " + name

def greet_with_default(name="World"):

return "Hello " + name

Complete the function is_positive(number) that returns True if the number is greater than 0, and False otherwise.

def is_positive(number):

# TODO: Return True if number > 0, False otherwise

pass

def is_positive(number):

return number > 0

Write a complete function calculate_discount(price, discount_percent) that calculates and returns the final price after applying a discount percentage.

For example, calculate_discount(75, 20) should return 60.0.

def calculate_discount(price, discount_percent):

# TODO: Calculate and return the final price after discount

pass

def calculate_discount(price, discount_percent):

return price * (1 - discount_percent / 100)

Write a complete function password_strength(password) that returns "Strong" if the password is at least 8 characters long and contains both letters and numbers, "Weak" otherwise.

For example, password_strength("abc123def") should return "Strong".

def password_strength(password):

# TODO: Return "Strong" or "Weak" based on password criteria

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

# TODO: Add your return logic here based on has_letter and has_number

pass

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"

Write a complete function convert_temperature(celsius) that converts Celsius to Fahrenheit using the formula: F = C * 9/5 + 32.

For example, convert_temperature(0) should return 32.0.

def convert_temperature(celsius):

# TODO: Convert Celsius to Fahrenheit using F = C * 9/5 + 32

pass

def convert_temperature(celsius):

return celsius * 9 / 5 + 32

Fix the indexing error in this function that should return the last character of a string.

def get_last_character(text):

return text[len(text)]

def get_last_character(text):

return text[-1]

Fix the missing return statement in this function that should return whether a number is even.

def is_even(number):

if number % 2 == 0:

True

else:

False

def is_even(number):

if number % 2 == 0:

return True

else:

return False

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

def find_maximum(a, b):

if a < b:

return b

else:

return a

Tip: Correctly returning the larger of two numbers using if-else

You can use either approach:

1️⃣ Using a < b:

if a < b:

return b

else:

return a

2️⃣ Using a > b:

if a > b:

return a

else:

return b

✅ Key point: The if condition and the corresponding return statements must align so the larger number is returned. Swapping the comparison requires swapping the return values accordingly.
