The idea here is to reset index such that they are all integers from 0 to N.

Two possible approaches:

To not modify the original df but assign the result to a new variable

df_new = df.reset_index(drop=True)

To do it in place

df.reset_index(drop=True, inplace=True)

df.index = np.arange(len(df))

Sample code: https://github.com/KamarajuKusumanchi/notebooks/blob/master/pandas/reindex%20from%200%20to%20N.ipynb
