• What is the output of the round() function?

```                ```market_share = 12.03298

rounded_market_share = round(market_share, 2)

print(rounded_market_share)``````
• How many arguments does the round function take in the given code snippet?

```                ```market_share = 12.03298

rounded_market_share = round(market_share, 2)

print(rounded_market_share)``````
• Find the lowest price.

```                ```product_prices = [27.99, 19.99, 23.99, 25.99, 26.99]

lowest_price = ''(product_prices)

print(lowest_price)``````
• Find the highest temperature.

```                ```daily_temperatures = [25, 28, 29, 26, 30, 27]

highest_temperature = ''(daily_temperatures)

print(highest_temperature)``````
• What is the return type of the input() function?

`                `contact_number = input('Please enter your contact number:')``
• What is type casting in Python?

• Cast the product price to a floating-point number.

```                ```product_price = '9.99'

casted_product_price = ''(product_price)``````
• Cast the image_resolution from string to integer.

```                ```image_resolution = '72'

casted_image_resolution = ''(image_resolution)``````
• What is wrong with this code?

```                ```message = 'You have ' + 5 + ' new messages.'

print(message)``````
• Debug this code.

`                `message = 'You are customer number: ' + ''(1005)``
• Debug this code.

`                `message = 'The product has a rating of ' + ''(4.5) + ' stars.'``
• Complete this code.

```                ```software_name = "SnapFood"
current_step = 2
total_steps = 5

update_message = 'Installing ' + software_name + ': Step ' + ''(current_step) + ' of ' + str(total_steps)

print(update_message)
``````
• Complete this code.

```                ```item_count = 5

cart_message = 'You have ' + ''(item_count) + ' items in your cart.'

print(cart_message)``````
• Suppose you are organizing an event.
Complete the code to determine the number of chairs needed based on the number of attendees and an additional 10 extra chairs.

```                ```attendees = input('How many people are attending the event? ')

chairs_needed = ''(attendees) + 10

print('You need ' + str(chairs_needed) + ' chairs for the event.')``````
• Complete the program based on the following logic:
Imagine you are organizing a school picnic, and you need to determine the total cost of food based on the number of students attending and the cost per meal.

* cost_per_meal could be a floating point number

```                ```num_students = input('Enter the number of students attending the picnic: ')
cost_per_meal = input('Enter the cost per meal: ')

total_cost = int(num_students) * ''(cost_per_meal)

print('The total cost of food for the picnic is: ' + str(total_cost))``````
