title: How to retrieve value of n-th element in pandas Series object?
body: <p>I have a series object (1 column of a <code>DataFrame</code>) and would like to extract the value of the first element. Is there a way to do this simply without converting to a list and without knowing the key? Or is the only way to access it by converting it to a list first using <code>tolist()[n]</code>?</p>
