pls help me create a simple dataframe with row numbers in each column
<p>How can I generate this dataframe on a much larger scale without typing in lists?</p>

<pre><code>df = pd.DataFrame([[0,0,0,0,0],[1,1,1,1,1],[2,2,2,2,2],[3,3,3,3,3],[4,4,4,4,4]], \
     index=pd.date_range(start='2000-01-01',periods=5),columns=['a','b','c','d','e'])
</code></pre>

<p>Thanks!</p>
