Drop all data in a pandas dataframe : <p>I would like to drop all data in a pandas dataframe, but am getting <code>TypeError: drop() takes at least 2 arguments (3 given)</code>. I essentially want a blank dataframe with just my columns headers.</p>

<pre><code>import pandas as pd

web_stats = {'Day': [1, 2, 3, 4, 2, 6],
             'Visitors': [43, 43, 34, 23, 43, 23],
             'Bounce_Rate': [3, 2, 4, 3, 5, 5]}
df = pd.DataFrame(web_stats)

df.drop(axis=0, inplace=True)
print df
</code></pre>
