What is reset_index?
reset_index (also called set_index): A pandas method that turns the current index into an ordinary column and replaces it with a plain 0, 1, 2 counter. It is commonly needed after groupby or filtering, when the labels are no longer useful as an index.
reset_index: an example
df.groupby('city')['sales'].sum().reset_index() returns a normal table with city and sales columns.
