[USER (data scientist)]: That looks good! Now, how do I get their IDs? Please generate an index object representing specific rows 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(result_idx)

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

---END CODE TEMPLATE---

[YOU (AI assistant)]: No problem! You can get the client IDs by grabbing the index of the filtered DataFrame. Try this:
'''
import pandas as pd 
import pickle
 
# Load the dataset 
credit_customers = pd.read_csv("credit_customers.csv") 
 
# YOUR SOLUTION BEGIN:
