This page contains $2017$ census information when the total population of the U$.$S$.$ was $325,719,178.$

The file nested$-$lists.py contains information about the $10$ most populous states.

Add a pure function to nested$-$lists.py that calculates and returns the total population of the information passed into it$.$ Print this value after the function returns it$.$

Modify the program to also print the percentage of the U$.$S$.$ population that lives in the $10$ most populated states.

Modify the populations variable to include information about whether each state is landlocked. Consider a landlocked state to be one that does not touch the Atlantic Ocean, the Pacific Ocean or the Gulf of Mexico.

Modify the program to also calculate and print the percentage of the population in the $10$ most populated states that live in a landlocked state.

Time permitting, make other interesting enhancements.
