#This program draws a diamond. The user specifies the number of levels, they must be
#an odd number

#For example:a diamond of 5 levels:
#
#
#  *
# ***
#*****
# ***
#  *
#

#Note: multiplying a string by a number creates a new one that repeats the original
#multiple times, for example, '*'*3 = '***'
