New Dataframe Column Based on Several Conditions
#1
I am trying to add a new column to my dataframe based on several complex conditions. I have attached a sample of what I have, along with the column I am trying to add (highlighted). I have a table with customer IDs and revenues for 2021, 2020, 2019, 2018, and 2017. I want to add a "customer status" column that is based off of the revenue columns, and will be populated with the following selections based on the following conditions:

- 2021 New – Positive revenue in 2021 but no (or negative) billings in 2020, 2019, 2018, and 2017.
- 2021 Lost – No (or negative) revenue in 2021, but positive revenue in 2020.
- 2021 Renewed – Positive revenue in 2021, no (or negative) revenue in 2020, and positive revenue in either or all of 2019, 2018, or 2017.
- N/A – Negative or zero revenue in 2021 and negative or zero revenue in 2020
- 2021 Existing – Positive revenue in 2021 and positive revenue in 2020

I have tried using np.select, for loops, and other methods, but the number of conditions is giving me trouble.
