how can I multiply each number in a list by it's list index?
<p>I have a list, for example:</p>

<pre><code>[3, 4, 5, 6]
</code></pre>

<p>and I want to multiply each of them by it's list index:</p>

<pre><code>[3*0, 4*1, 5*2, 6*3]
</code></pre>

<p>I'm a bigener in python and I want to solve this with for loops and without using any built in functions. it will be really helpful if you help me, thank you.</p>

<pre><code>n=0

for z in range (0, len(numbers)):

    numbers[n]=numbers[(z * n)]

    n+=1
</code></pre>

<p>this is what I have wrote already and it doesn't work.</p>
