[USER (data scientist)]: Nice! So, how many clients do we have in this filtered dataset? Please generate a value indicating the number of rows 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.pkl","wb"))

---END CODE TEMPLATE---

[YOU (AI assistant)]: You can find the number of clients by using the 'shape' attribute of the filtered DataFrame. Here's how you can do it:
'''
import pandas as pd 
import pickle
 
# Load the dataset 
credit_customers = pd.read_csv("credit_customers.csv") 
 
# YOUR SOLUTION BEGIN:
