If we realize later that we liked the old pandas default index, we can just reset_index . pandas.DataFrame.reset_index¶. Reset the index, or a level of it. Reset the index of the DataFrame, and use the default one instead. If the DataFrame has a MultiIndex, this method can remove one or more levels. Only remove the given levels from the index. Removes all levels by default. Pandas is one of those packages and makes importing and analyzing data much easier. Pandas reset_index() is a method to reset index of a Data Frame. reset_index() method sets a list of integer ranging from 0 to length of data as index.
pandas.Series.reset_index¶. Generate a new DataFrame or Series with the index reset. This is useful when the index needs to be treated as a column, or when the index is meaningless and needs to be reset to the default before another operation. For a Series with a MultiIndex, only remove the specified levels from the index.

Pandas Series.reset_index() function generate a new DataFrame or Series with the index reset. This comes handy when index is need to be used as a column. This comes handy when index is need to be used as a column. reset_index() is what you're looking for. If you don't want it saved as a column, then do: df = df.reset_index(drop=True) If you don't want to reassign: df.reset_index(drop=True, inplace=True) Well, pandas has built-in reset_index () function. So to reset the index to the default integer index beginning at 0, you can simply use the built-in reset_index () function. This will make the integer index the default index and take the existing index and make it a column.
