Convert array of int to array of chars - Python
<p>I am trying to convert a set literal of integers into that of chars. </p>

<p>For example, if the array {0,1} is given as an input, I would like to firstly check if the individual elements are chars and if not convert them into chars so that I get {'0', '1'}</p>

<p>So far I have tried:</p>

<pre><code>for i in alpha:

    i = str(i)
</code></pre>

<p>Where alpha is my array. However this does not change the overall array alpha.</p>

<p>Can sometime please give me an idea of how I can do this.</p>

<p>Thanks in advance for any help</p>
