Challenge 124 - Planetary Weight Converter

In this challenge, you have to convert a weight weighed on a planet of the Solar System to the corresponding weight on another planet.

To convert the weight, you have to divide it by the gravitational force of the planet on which it is weighed and multiply the result (the mass) with the gravitational force of the other planet. See the table below for a list of gravitational forces:

weight on planet_a / gravitational force of planet_a * gravitational force of planet_b

Planet	  m/s²
Mercury 3.7

Challenge 123 - List Builder

Write a function that takes a list of multiple lists and returns one list that is made up of all the lists in the original list. Put another way you need to flatten a 2d list.

Examples

list_builder([[1, 2], [3, 4]]) ➞ [1, 2, 3, 4]

list_builder([["a", "b"], ["c", "d"]]) ➞ ["a", "b", "c", "d"]
