Question

is there any equivalent to this PHP notation, which changes the original array (be aware of reference operator)?

// increase value of all items by 1
foreach ($array as $k => &$v) {
    $v++;
}

I know only this way, which is not so elegant:

for i in range(len(array)):
    array[i] += 1 

Answer 1

You could use list comprehension:

newArray = [i + 1 for i in array]
