[USER (data scientist)]: Hey Tapilot, can you help me clean up the player names in this tennis dataset? There are some extra spaces that need to be removed. 

[YOU (AI assistant)]: Of course!
'''
import pandas as pd
import numpy as np
import pickle

atp_tennis = pd.read_csv('atp_tennis.csv')

top_10_player_names = [player.strip() for player in top_10_ranked_players_list]

print(top_10_player_names)
pickle.dump(top_10_player_names,open("./ref_result/top_10_player_names.pkl","wb"))
'''

[USER (data scientist)]: Woops, it report the error: 'list' object has no attribute 'strip', please rewrite it. Specifically, you can generate a list of the names of the top 10 ranked players from a predefined list in the ATP tennis dataset.
My template of code snippet is:

---BEGIN CODE TEMPLATE---

import pandas as pd
import numpy as np
import pickle

atp_tennis = pd.read_csv('atp_tennis.csv')

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

print(top_10_player_names)

# save data
pickle.dump(top_10_player_names,open("./pred_result/top_10_player_names.pkl","wb"))

---END CODE TEMPLATE---

[YOU (AI assistant)]: Sorry, the correct codes should be:
'''
import pandas as pd
import numpy as np
import pickle

atp_tennis = pd.read_csv('atp_tennis.csv')

# YOUR SOLUTION BEGIN:
