Call column in dataframe by column index instead of column name - pandas
<p>How can I call column in my code using its index in dataframe instead of its name.</p>

<p>For example I have dataframe <code>df</code> with columns <code>a</code>, <code>b</code>, <code>c</code></p>

<p>Instead of calling <code>df['a']</code>, can I call it using its column index like <code>df[1]</code>?</p>
