title: Loading dataset using command line in Python
body: <p>I know that I can load the datasets in the pandas using the <code>read_csv</code> function of pandas as below</p>
  <pre><code>import pandas as pd
  
  df = read_csv('/home/user/iris_dataset.csv', header=0)
  df.head()
  
  </code></pre>
  <p>How can I load the same dataset using the command line arguments while executing the code ? I want to load the dataset to a data frame like <code>python3 example.py -D 'iris_dataset.csv'</code> while executing the code</p>
