This is code I write for the question. From this screenshot, the answer should be 0.

When I put the number for question 23, it is incorrect. 

 

I'm not sure if I did something wrong. Please advice and assist me.

 

Thank you

Hi @JINNINGXIAN!

This is the link for the data. https://public.dhe.ibm.com/software/data/sw-library/cognos/mobile/C11/data/Telco_customer_churn.xlsx

When I check it with this code I get 11. I wonder if you have accidentally modified the DataFrame in another block of code?
