# WSQ07 – Lists

--Originally published at マルコ

What to Do

Create a program that asks the user for 10 numbers  (floating point). Store those numbers in a list. Show to the user the total, average and standard deviation of those numbers.

Details

For the Python group, you want to be using Lists. For the C++ group you can do this with arrays or Vectors, but you will need to know eventually how to do both.

Once you have this working, change it so that users keep giving you values until they signal “no more values”. How would you implement this and in particular for the C++ group, how to you deal with an unknown size to your array during compilation?

WSQ-07

--Originally published at Héctor Santillán

En esta ocasión se debe desarrollar un programa que tome diez números y entregue la suma de ellos, su promedio y su desviación estándar.

Se empieza por importar statistics, con el cual tendremos acceso a las operaciones de promedio y desviación estándar. Luego de pedir los números, los incluimos en una lista y finalmente realizamos las operaciones con statistics.mean() y statistics.stdev().

Para desarrollar este programa me apoyé en conocimientos previos y una breve investigación del módulo statistics.


WSQ07 – Lists (unfinished)

For this assignment theses were my instructions:

Create a program that asks the user for 10 numbers  (floating point). Store those numbers in a list. Show to the user the total, average and standard deviation of those numbers.

Once you have this working, change it so that users keep giving you values until they signal “no more values”.

This is what I came up with:

Lists!

Another program I made was one that would ask the user to introduce 10 numbers, then it would store those numbers in a list and output the total, average, and standard deviation of them.

First things first, I learned about lists in python from this page:

https://www.tutorialspoint.com/python/python_lists.htm

Also, I didn’t actually know the formula for standard deviation, so I looked it up and found these useful pages:

http://www.gmatfree.com/module-999/gmat-standard-deviation/

Finally, this other page helped me by giving me an idea of how to do it:

At the end, my program looked like this:

lists

And worked like this:
