Dice Game 6 - High Score Table

#  HST Playing - write a score and a name to an external file
#  then present the current 5 highest scores.

# what we know

a_list = [[15, "Gerald"],[20, "Stefano"],[5, "Marmaduke"]] # this is a list of lists similar to an array

print(len(a_list)) ## your go

print(a_list)                       # [[15, 'Gerald'], [20, 'Stefano'], [5, 'Marmaduke']]
a_list.sort()                       # sorts increasing
print(a_list)                       #[[5, 'Marmaduke'], [15, 'Gerald'], [20, 'Stefano']]
a_list.sort(reverse = True)         # sorts decreasing
print(a_list)                       # [[20, 'Stefano'], [15, 'Gerald'], [5, 'Marmaduke']]

# so we can use this for our HST (there are other ways to do this, but this one I undertsand)
