What is Reset Index ?
In Python programming language and the pandas library, the reset_index
method is used to reset the index of a data frame. When you perform operations on a DataFrame in pandas, the index of the DataFrame may change or become unordered. The reset_index
method allows you to reset the index to the default integer-based index and reset the index in Pandas DataFrame optionally removing the current index.
Reset Index in Pandas Dataframe
Let’s discuss how to reset the index in Pandas DataFrame. Often We start with a huge data frame in Pandas and after manipulating/filtering the data frame, we end up with a much smaller data frame. When we look at the smaller data frame, it might still carry the row index of the original data frame. If the original index is numbers, now we have indexes that are not continuous.
