[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 a value representing the number of entries in a specific subset of the dataset.
My template of code snippet is:

---BEGIN CODE TEMPLATE---

import pandas as pd 
import pickle
 
# Load the dataset 
credit_customers = pd.read_csv("credit_customers.csv") 
 
# YOUR SOLUTION BEGIN:
<code1>
[COMPLETE YOUR CODE]
</code1>
# YOUR SOLUTION END

print(f"result_count: {result_count}") 

# save data
pickle.dump(result_count, open("./pred_result/result_count_2.pkl","wb"))

---END CODE TEMPLATE---

[YOU (AI assistant)]: Sure thing! To get the count of clients in the combined dataset, use this code:
'''
import pandas as pd 
import pickle
 
# Load the dataset 
credit_customers = pd.read_csv("credit_customers.csv") 
 
# YOUR SOLUTION BEGIN:
