Pandas DataFrame has a built-in function pandas.DataFrame.between_time

df = pd.DataFrame(np.random.randn(1000, 2),
                  index=pd.date_range(start='2017-01-01', freq='10min', periods=1000))

Create 2 data frames for each period of time:

df1 = df.between_time(start_time='10:00', end_time='13:00') 
df2 = df.between_time(start_time='20:00', end_time='23:00')

Data frame you want is merged and sorted df1 and df2:

pd.concat([df1, df2], axis=0).sort_index()
