Look this one

b=lambda n:'\n%s bottle%s of beer on the wall'%(n%100 or'No more','s'*(n!=1))
for n in range(99,-1,-1):print(b(n)*2)[:-12]+'\n'+'Take one down, pass it \
around'*(n!=0)+'Go to the store and buy some more'*(n==0)+b(n-1)

For above code, you need to indent certain lines. The post cannot show indents.
