Creating a new column based on the values of other columns

Question

I wanted to create a \"High Value Indicator\" column, which says \"Y\" or \"N\" based on two different value columns. I want the new column to have a \"Y\" when Value_1 is >

Answer 1

You can also use apply:

df['High Value Indicator'] = (
     df.apply(lambda x: 'Y' if (x.Value_1>1000 or x.Value_2>15000) else 'N', axis=1)
     )
