Is there any pythonic way to make "Slice" from an array?

Question

In Javascript there is the Array.prototype.slice:

var input = [ 'laranja', 'limão', 'melancia', 'mamão' ];

var aparada = input.slice(1, -1);

console.log( aparada );

And in the PHP the array_slice:

$input = array( 'laranja', 'limão', 'melancia', 'mamão' );

print_r( array_slice($input, 0, -1) );

How could I do this in Python, in a more simplified way?

Answer 1

Python has the function slice, but I believe that the most simplified way of extracting a set of elements should be to use the same notation to obtain a single element: lista[<Índice>], but must inform the desired range: lista[<Inicio>:<Fim>]

input = [ 'laranja', 'limão', 'melancia', 'mamão' ]
print(input[1:-1])

Online example repl it.

Continuing the same notation above, there is the third parameter which is the footstep: lista[<Inicio>:<Fim>:<Passo>], the footstep has its initial value as 1, and if informed the value 0 a exception like this:

Traceback (most recent call last):
  File "python", line 3, in <module>
ValueError: slice step cannot be zero

Example with footstep:

numeros = [ 1, 2, 3, 4, 5, 6, 7, 8, 9]
print(numeros[::2]) # Impares
print(numeros[1::2]) # Pares

Online example repl it.

Example using the function slice.

input = [ 'laranja', 'limão', 'melancia', 'mamão' ]
print(input[slice(1,-1)])

Online example repl it.

Example using footstep in function slice.

numeros = [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ]
print(numeros[slice(None,None,2)]) # Impares
print(numeros[slice(1,None,2)]) # Pares

Online example repl it.
