#  Merge, join, concatenate and compare  #

pandas provides various methods for combining and comparing [ ` Series  `
](../reference/api/pandas.Series.html#pandas.Series "pandas.Series") or [ `
DataFrame  ` ](../reference/api/pandas.DataFrame.html#pandas.DataFrame
"pandas.DataFrame") .

  * [ ` concat()  ` ](../reference/api/pandas.concat.html#pandas.concat "pandas.concat") : Merge multiple [ ` Series  ` ](../reference/api/pandas.Series.html#pandas.Series "pandas.Series") or [ ` DataFrame  ` ](../reference/api/pandas.DataFrame.html#pandas.DataFrame "pandas.DataFrame") objects along a shared index or column 

  * [ ` DataFrame.join()  ` ](../reference/api/pandas.DataFrame.join.html#pandas.DataFrame.join "pandas.DataFrame.join") : Merge multiple [ ` DataFrame  ` ](../reference/api/pandas.DataFrame.html#pandas.DataFrame "pandas.DataFrame") objects along the columns 

  * [ ` DataFrame.combine_first()  ` ](../reference/api/pandas.DataFrame.combine_first.html#pandas.DataFrame.combine_first "pandas.DataFrame.combine_first") : Update missing values with non-missing values in the same location 

  * [ ` merge()  ` ](../reference/api/pandas.merge.html#pandas.merge "pandas.merge") : Combine two [ ` Series  ` ](../reference/api/pandas.Series.html#pandas.Series "pandas.Series") or [ ` DataFrame  ` ](../reference/api/pandas.DataFrame.html#pandas.DataFrame "pandas.DataFrame") objects with SQL-style joining 

  * [ ` merge_ordered()  ` ](../reference/api/pandas.merge_ordered.html#pandas.merge_ordered "pandas.merge_ordered") : Combine two [ ` Series  ` ](../reference/api/pandas.Series.html
