Answer 1

Try using:

df1.reset_index(drop=True)

This resets the index to the default integer index and removes the original one. If you want to assign this change to original dataframe it is easier to use:

df1.reset_index(drop=True, inplace=True)

As it will edit the df1 dataframe without making a copy of it.
