4.5.4 Correct Portion CodeHS Answers

The most common answer is:

Amount of food and number of people
tons_of_food = 0.07
num_people = 25
Determine how much food each person gets
tons_of_food_per_person = tons_of_food / num_people
print tons_of_food_per_person
Ask the user how much food they took
tons_taken = float(input(“How many tons of food did you take? “))
round(tons_of_food_per_person, 5)
round(tons_taken, 5)
if tons_taken == tons_of_food_per_person:
print “Good job, you took the right amount of food!”
else:
print “You took the wrong amount of food!”

To ensure the program runs correctly in Python, especially in Python 3, you need to add parentheses around the arguments to the print function and ensure that the round function’s result is used in the comparison.

Here’s the corrected version of the code:

# Amount of food and number of people
tons_of_food = 0.07
num_people = 25

# Determine how much food each person gets
tons_of_food_per_person = tons_of_food / num_people
print(tons_of_food_per_person)

# Ask the user how much food they took
tons_taken = float(input("How many tons of food did you take? "))

# Round the values for comparison
rounded_tons_of_food_per_person = round(tons_of_food_per_person, 5)
rounded_tons_taken = round(tons_taken, 5)

# Compare and print the result
if rounded_tons_taken == rounded_tons_of_food_per_person:
    print("Good job, you took the right amount of food!")
else:
    print("You took the wrong amount of food!")

This corrected code includes the following adjustments:

Using parentheses with the print function, as required by Python 3 syntax.
Storing the results of the round function into variables for comparison. This ensures that when comparing tons_taken with tons_of_food_per_person, both numbers are rounded to the same number of decimal places, making the comparison accurate.
Asking the user for their input on how much food they took, rounding that input, and then comparing it to the rounded amount of food per person to determine if they took the correct amount.
