Implementing stack in python by using lists as stacks 
<p>I am create a stack demo with some functionality:</p>

<pre><code>( Method ) __init__(self, n) =&gt; How can I initial the fix  n len of stack. ?
( Method ) IsEmpty      =&gt; Done by using lists as stacks 
( Method ) IsFull       =&gt; Done by using lists as stacks 
( Method ) Push         =&gt; Done by using lists as stacks 
( Method ) Pop          =&gt; Done by using lists as stacks 
</code></pre>

<p>The code i am doing </p>

<pre><code> class Stack(object) :

   def __init__(self) :
    self.items = []
   def push(self, item) :
    self.items.append(item)

   def pop(self) :
    return self.items.pop()

   def isEmpty(self) :
    return (self.items == []) 

if __name__ == "__main__":
    demoStack = Stack()
    demoStack.push(1)
    print demoStack.items
</code></pre>
