HackerRank Text Alignment in python problem solution 

#Replace all ______ with rjust, ljust or center. 

thickness = int(raw_input()) #This must me an odd number
c = 'H'

#Top Cone
for i in range(thickness):
    print (c*i).rjust(thickness-1)+c+(c*i).ljust(thickness-1)

#Top Pillars
for i in range(thickness+1):
    print (c*thickness).center(thickness*2)+(c*thickness).center(thickness*6)

#Middle Belt
for i in range((thickness+1)/2):
    print (c*thickness*5).center(thickness*6)    

#Bottom Pillars
for i in range(thickness+1):
    print (c*thickness).center(thickness*2)+(c*thickness).center(thickness*6)    

#Bottom Cone
for i in range(thickness):
    print ((c*(thickness-i-1)).rjust(thickness)+c+(c*(thickness-i-1)).ljust(thickness)).rjust(thickness*6)
