[USER (data scientist)]: Awesome! Lastly, I need to know how many clients are in this combined dataset. Can you help me with that? Please generate the code with the output in value type.
My template of code snippet is:

---BEGIN CODE TEMPLATE---

import pandas as pd  
import pickle
from decision_company import read_csv_file, fetch_column, logical_or, filter_by_condition, count_rows
