All in Python.

Q$1.$ Get user input for a list of numbers. Write a program to turn every item of a list into its square. You cannot assume the size of the list. You must get the list of numbers from the user by using the concept of indefinite loop.

Q$2.$ Part $1-$

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.

Example:$-$

Enter weight $1$:

$236\mathrm{.}0$

Enter weight $2$:

$89\mathrm{.}5$

Enter weight $3$:

$176\mathrm{.}0$

Enter weight $4$:

$166\mathrm{.}3$

Weights: $[236\mathrm{.}0,89\mathrm{.}5,176\mathrm{.}0,166\mathrm{.}3]$

Part $2-$

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

Part $3-$ Output the max list element with two digits after the decimal point

Part $4-$ Prompt the user for a number between $1$ and $4.$ Output the weight at the user specified location.

Part $5-$ Sort the list's elements from least heavy to heaviest weights and output the sorted list.
