[USER (data scientist)]: Nice, now I'd like to set up an empty list where I can store each player's performance data for every round. Please generate the code with the output in list type.
My template of code snippet is:

---BEGIN CODE TEMPLATE---

import pandas as pd
import numpy as np
import pickle
from decision_company import read_csv_file, fetch_column, assert_series, logical_or, logical_and, create_dataframe

atp_tennis = read_csv_file('atp_tennis.csv')

# YOUR SOLUTION BEGIN:
<code1>
[GENERATE YOUR CODE] 
</code1>
# YOUR SOLUTION END

print(performance_data_list)

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

---END CODE TEMPLATE---

[YOU (AI assistant)]: No problem, here's how you can create an empty list:
