python byRef // copy
<p>I am new to Python (and dont know much about programming anyway), but I remember reading that python generally does not copy values so any statement a = b makes b point to a. If I run</p>

<pre><code>a = 1
b = a
a = 2
print(b)
</code></pre>

<p>gives the result 1. Should that not be 2?</p>
