Wie konvertiert man eine Pandas DataFrame-Spalte oder -Zeile in eine Liste?

<code class="python">import pandas as pd

data_dict = {'cluster': ['A', 'A', 'A', 'B', 'B', 'B', 'C', 'C', 'C'],
             'load_date': ['1/1/2014', '2/1/2014', '3/1/2014', '4/1/2014', '4/1/2014', '4/1/2014', '7/1/2014', '8/1/2014', '9/1/2014'],
             'budget': [1000, 12000, 36000, 15000, 12000, 90000, 22000, 30000, 53000],
             'actual': [4000, 10000, 2000, 10000, 11500, 11000, 18000, 28960, 51200],
             'fixed_price': ['Y', 'Y', 'Y', 'N', 'N', 'N', 'N', 'N', 'N']}

df = pd.DataFrame(data_dict)
cluster_list = df['cluster'].tolist()
print(cluster_list)</code>

['A', 'A', 'A', 'B', 'B', 'B', 'C', 'C', 'C']

<code class="python">cluster_list = list(df['cluster'])</code>

<code class="python">row1_list = df.iloc[0].tolist()
print(row1_list)</code>

[1000, '4000', 'Y']

<code class="python">row1_list = list(df.iloc[0])</code>
