why is the .loc() function returning an empty Series

enter image description here

when I excute basic_data.loc[2:61, 'v_00'] it return Series([], Name: v_00, dtype: float64)

Why?

I wonder why I got empty series.

2:61 will slice the rows (by position) that are between the row index 2 and the row index 61, which are none. It will not consider the values between the integer 2 and 61.

I believe you want between:

basic_data.loc[basic_data.index.to_series().between(2, 61), 'v_00']

# or
basic_data.loc[(basic_data.index >= 2) & (basic_data.index <= 61), 'v_00']

Or first sort your index:

basic_data = basic_data.sort_index()
basic_data.loc[2:61, 'v_00']
