a=[1,2,3,4]
print(list([a[1+i-4],a[2+i-4],a[3+i-4]] for i in range(4))).

The above solution might not work for other cases.

Answer 2

You can use combination in itertools

from itertools import combinations

combinations(urlist, k)

Answer 3

Yes, combinations creating a pairs but i want to print above order, combinations will print this order (1, 2, 3),(1, 2, 4),(1, 3, 4),(2, 3, 4) it's different from my solution

Answer 4

What do you mean what is the order how do you define what comes first
