This returns a copy of the data. Operations in general exclude missing data.
Operating with objects that have different dimensionality and need alignment. In addition, pandas automatically broadcasts along the specified dimension. Series is equipped with a set of string processing methods in the str attribute that make it easy to operate on each element of the array, as in the code snippet below. Note that pattern-matching in str generally uses regular expressions by default and in some cases always uses them.
See more at Vectorized String Methods. SQL style merges. See the Database style joining. Append rows to a dataframe. Grouping by multiple columns forms a hierarchical index, which we then apply the function. See the sections on Hierarchical Indexing and Reshaping. See the section on Pivot Tables.
