Question

8.8 LAB: Warm up: People's weights (Lists)

(1) Prompt the user to enter four numbers, each corresponding to a person's weight in pounds. Store all weights in a list. Output the list. (2 pts)

Ex:

Enter weight 1:

236.0

Enter weight 2:

89.5

Enter weight 3:

176.0

Enter weight 4:

166.3

Weights: [236.0, 89.5, 176.0, 166.3]

(2) Output the average of the list's elements with two digits after the decimal point. Hint: Use a conversion specifier to output with a certain number of digits after the decimal point. (1 pt)

(3) Output the max list element with two digits after the decimal point. (1 pt)

Ex:

Enter weight 1:

236.0

Enter weight 2:

89.5

Enter weight 3:

176.0

Enter weight 4:

166.3

Weights: [236.0, 89.5, 176.0, 166.3]

Average weight: 166.95

Max weight: 236.00

(4) Prompt the user for a number between 1 and 4. Output the weight at the user specified location and the corresponding value in kilograms. 1 kilogram is equal to 2.2 pounds. (3 pts)

Ex:

Enter a list location (1 - 4):

3

Weight in pounds: 176.00

Weight in kilograms: 80.00

(5) Sort the list's elements from least heavy to heaviest weight. (2 pts)

Ex:

Sorted list: [89.5, 166.3, 176.0, 236.0]

Output the average and max weights as floating-point values with two digits after the decimal point, which can be achieved as follows:

print('{:.2f}'.format(your_value))

need the code in python please

Answer 1

weights = [float(input('Enter weight 1: \n')),
           float(input('Enter weight 2: \n')),
           float(input('Enter weight 3: \n')),
           float(input('Enter weight 4: \n'))]
print("Weights:", weights)

print('\nAverage weight: {:.2f}'.format(sum(weights) / len(weights)))

print('Max weight: {:.2f}'.format(max(weights)))

index = int(input('\nEnter a list location (1 - 4): \n'))
print('Weight in pounds: {:.2f}'.format(weights[index - 1]))
print('Weight in kilograms: {:.2f}'.format((weights[index - 1] / 2.2)))

print('\nSorted list:', sorted(weights))
