Print values in Python list reporting ValueError
<p>I have two lists :</p>

<pre><code>a = [0,1]
b = ['a' , 'b']
</code></pre>

<p>and would like the following output:</p>

<pre>
0
a
1
b
</pre>

<p>I tried the following and it gives a <code>ValueError</code>:</p>

<pre><code>for k,v in (a,b):
    print (k,v)
</code></pre>

<p>What am I doing wrong?</p>
