I\'m trying to figure out how to turn my whole square into a hollow one. The few things I\'ve tried so far haven\'t been very successful as I end up getting present
You can print out a single '*', followed by size-2 spaces, then a single '*'. This will give you the "hollow" portion. The first and last lines need the full length:
size = 5
inner_size = size - 2
print ('*' * size)
for i in range(inner_size):
print ('*' + ' ' * inner_size + '*')
print ('*' * size)
