list without repetitions

[sokadin]

Good day dear people, i just need little help with my code. I have to make list without repetitions from the one that has repetitions. I don't know where am i making a mistake. this is code:

liss=[6,7,5,3,6,8,9,6,4,3,2,5,6,8,9,0,1,98]
	
def lwr(liss):
	liss.sort(key=None,reverse=False)
	print(liss)
	i=1
	liss1=[]
	for n in liss:
		if n!=liss[i]:
			liss1.append(n)
            i+=1
		else:
			continue
	return print(liss1)
lwr(liss)

Thank you.
