Can it be more optimised?

Question

Classment of multiples
https://code.sololearn.com/c3AirizByeDE/?ref=app

Answer 1

You could replace lines:

if i%2 == 0 :
classment["even"].append(i)
else :
classment["odd"].append(i)

With:

if i&1:
classment["odd"].append(i)
else:
classment["even"].append(i)

Answer 2

multiple = {}

for i in range(2,10):
multiple[i] = []
for j in range(0,20,i):
multiple[i].append(j)

print(multiple)

You can improve it using a list comprehension.
