import random
POINTS=[20,40,10,30,15];
POINTS=[30,50,20,40,45];

BEGIN=random.randint(1,3)
LAST=random.randint(2,4)
for C in range(BEGIN,LAST+1):
print POINTS[C],"#",

(i) ​20#50#30# (ii) ​20#40#45#
(iii) ​50#20#40# (iv) ​30#50#20#

Ans (ii) 20#40#45# and (iii) 50#20#40#

Max value for BEGIN 3
Max value for LAST 4
