Hi@akhtar,
Your data set contains lots of rows and columns, but jupyter shows you some of your data by default. You can see your whole dataset by adding the below given codes.
import pandas as pd
pd.set_option('display.max_rows', None)
pd.set_option('display.max_columns', None)
pd.set_option('display.width', None)
Now try with this, it will work.
