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

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]

 

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.

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

 

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

 

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))

 

Use Python, please.

**Educational Exercise: Analyzing and Manipulating Lists in Python**

**Objective:**
This exercise aims to help students learn how to manage and analyze a list of weights using Python programming skills. Follow the steps below to complete the tasks.

**Instructions and Tasks:**

1. **Prompt for Four Weights:**
   - Collect four weight values from the user.
   - Add these values to a list and output the list to confirm the weights are stored correctly.

2. **Calculate and Output the Average:**
   - Compute the average of the weights in the list.
   - Print the average to provide insight into the general weight value.

3. **Identify the Maximum Weight:**
   - Determine the maximum weight from the list.
   - Output this maximum value to recognize the heaviest entry.

4. **Convert and Output Specific Weight:**
   - Ask the user for a specific index in the list.
   - Retrieve the weight at this index and output it in both pounds and kilograms for comparison and understanding of measurement conversions.

5. **Sort and Display the List:**
   - Sort the list of weights in ascending order.
   - Output the sorted list to show the weights organized from lightest to heaviest.

**Coding Implementation:**
These tasks should be programmed in the `main.py` file. Begin with comments like `# FIXME` to easily identify required sections and ensure clarity for further improvements.
