Hello, I have a dataframe with a column named 'Screening Date' in that column are dates and null values. I want to create a new column called 'Completed' that looks through 'Screening date' and if there is a date in a particular row I want to Write "Yes" in my new column. If the 'Screening date' column is null I want to write "No" in my new column.
I have tried using SQL syntax like Alter table and add column but it doesn't look like all SQL keywords are available.
