String slicing

[ibutun]

Is this something you want?

list1 = list(range(14,0,-1))
list2 = list(range(0,-17,-1))
a = list1 + list2
print(list1)
print(list2)
print(a)

Output:
[14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1]
[0, -1, -2, -3, -4, -5, -6, -7, -8, -9, -10, -11, -12, -13, -14, -15, -16]
[14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, -1, -2, -3, -4, -5, -6, -7, -8, -9, -10, -11, -12, -13, -14, -15, -16]

or like this?

print(*range(14,0,-1))
print(*range(0,-17,-1))
print(*range(14,-17,-1))

Output:
14 13 12 11 10 9 8 7 6 5 4 3 2 1
0 -1 -2 -3 -4 -5 -6 -7 -8 -9 -10 -11 -12 -13 -14 -15 -16
14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 -1 -2 -3 -4 -5 -6 -7 -8 -9 -10 -11 -12 -13 -14 -15 -16
