L1 = [3, 3, 8, 1, 3, 0, '1', '0', '2', 'e', 'w', 'e', 'r']
print(L1[: :-1])
print(L1[-1:-2:-3])
print(L1[-1:-2:-3:-4])

The line print(L1[-1:-2:-3:-4]) causes an error as its syntax is invalid. The correct syntax for slicing a list is L1[start:stop:step].

L1 = [1, 11, 21, 31]
An = L1.remove(31)
print(An + 2)

L1 = [3, 4, 5]
L2 = L1 * 3
print(L1 * 3.0)
print(L2)

x = ['3', '2', '5']
y = ''
while x:
    y = y + x[-1]
    x = x[:len(x) - 1]
print(y)
print(x)
print(type(x), type(y))
