String Conversion

Learn how to apply a string data type to a column.

Method 1: Using apply()

Whenever we want to combine a numerical column that contains an integer data type with another column containing a string data type, we perform string conversion. For example, suppose a DataFrame contains the columns, house_no, estate, and town, with integer, string, and string data types, respectively. In that case, we can convert house_no from an integer data type to a string data type to combine it with the other columns and create a new address column. If we attempted to combine columns with string and integer types, we would get an error.

Let's run the code below to perform string conversion.

Note: We don't check the column data types because we're familiar with the dataset.
