trying to unpack this. pd.Series.index returns integers when I pass a log return series to this function and thus (end_date - start_date) evaluates to a single element tuple
def get_years_past(series: pd.Series) -> float:
"""
Calculate the years past according to the index of the series for use with
functions that require annualization
"""
start_date = series.index[0]
end_date = series.index[-1]
return (end_date - start_date).days / 365.25
```
