Mistake in multivariate timeseries data set generation function in your book hands on time series analysis chapter 7

[manishhnnegi]

In Custom_ts_multi_data_prep function for multivatrate time series analysis in chapter 7 need correction in every chapter discussed in that chapter.
X takes out indices (0, 47+1) and y takes indices (49, 59), rather y should take values from (48, 58)
range (0, 48) means it takes 0-47 indices since 48 is exclusive.

indicey = range(i+1, i+1+ horizon)

it is supposed to be

indicey = range(i, i+horizon)
