Jupyter notebook taking forever to iterate over a for loop : <p>I an using the following for loop to iterate over df (droping a row if condition match) :</p>

<pre><code>for index, row in df.iterrows():
   if(pd.isnull(row["CR Date"])):
     df.drop(index, inplace=True)
</code></pre>

<p>the df shape 240,000*30
It is working BUT It is taking more than 1.5 hours.
Is there any faster way?
I am using Anaconda JupyterLab</p>
