(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. 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. (3) Output the max list element with two digits after the decimal point. 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. 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. 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)) code: wt = [] for i in range(4):val = float(input('Enter weight ' + str(i + 1) + ':')) wt.append(val) print('Weights:', wt) total = 0.0 for i in range(len(wt)):total = total + wt[i] avg = total / len(wt) print('Average weight:{:.2f}'.format(avg)) max = wt[0] for i in range(len(wt)): if wt[i] > max:max = wt[i] print('Max Weight:{:.2f}'.format(max)) ind = int(input('Enter a list index location (1 - 4):')) if ind < 1 or ind > 4: print('Invalid index!') else: print('Weight in pounds:', wt[ind - 1] ) print('Weight in kilograms:', (wt[ind - 1] / 2.2)) for i in range(len(wt)): min_Pos = i for j in range(i + 1, len(wt)): if wt[j] < wt[min_Pos]:min_Pos = j if i != min_Pos:temp = wt[i] wt[i] = wt[min_Pos] wt[min_Pos] = temp print('Sorted list:', wt) output: Program errors: Traceback (most recent call last): File "main.py", line 29, in <module> ind = int(input('Enter a list index location (1 - 4):')) EOFError: EOF when reading a line Program output: Enter weight 1:Enter weight 2:Enter weight 3:Enter weight 4:Weights: [236.0, 89.5, 176.0, 166.3] Average weight:166.95 Max Weight:236.00 Enter a list index location (1 - 4):

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))
code:
wt = []
for i in range(4):
val = float(input('Enter weight ' + str(i + 1) + ':'))
wt.append(val)
print('Weights:', wt)
total = 0.0
for i in range(len(wt)):
total = total + wt[i]
avg = total / len(wt)
print('Average weight:{:.2f}'.format(avg))
max = wt[0]
for i in range(len(wt)):
if wt[i] > max:
max = wt[i]
print('Max Weight:{:.2f}'.format(max))
ind = int(input('Enter a list index location (1 - 4):'))
if ind < 1 or ind > 4:
print('Invalid index!')
else:
print('Weight in pounds:', wt[ind - 1] )
print('Weight in kilograms:', (wt[ind - 1] / 2.2))
for i in range(len(wt)):
min_Pos = i
for j in range(i + 1, len(wt)):
if wt[j] < wt[min_Pos]:
min_Pos = j
if i != min_Pos:
temp = wt[i]
wt[i] = wt[min_Pos]
wt[min_Pos] = temp
print('Sorted list:', wt)
