Left Outer Join

In data science, a left outer join is a type of join operation used to combine two tables or data sets based on a common attribute or column. The result of a left outer join includes all the rows from the left table and the matching rows from the right table. If there is no match in the right table, the result will still include the row from the left table, but with null values for the columns from the right table. This type of join is useful for analyzing data from multiple sources and identifying relationships between them.
