Let’s see the different methods to join two text columns into a single column.
Method #1: Using cat() function
We can also use different separators during join. e.g. -, _, ” ” etc.
Method #2: Using lambda function
This method generalizes to an arbitrary number of string columns by replacing df[[‘First’, ‘Last’]] with any column slice of your dataframe, e.g. df.iloc[:, 0:2].apply(lambda x: ‘ ‘.join(x), axis=1).
Method #3: Using + operator
We need to convert data frame elements into string before join. We can also use different separators during join, e.g. -, _, ‘ ‘ etc.
