您可以使用以下代码来提取DataFrame的某一列:
```python
import pandas as pd
# 创建一个示例DataFrame
df = pd.DataFrame({'A': \[1, 2, 3, 4\], 'B': \[5, 6, 7, 8\], 'C': \[9, 10, 11, 12\]})
# 提取第一列,并将其转换为列表
column_list = df\['B'\].tolist()
print(column_list)
```
这段代码中,我们首先导入pandas库,然后创建了一个示例的DataFrame。接着,我们使用`df\['B'\]`来提取DataFrame的'B'列,并使用`tolist()`方法将其转换为一个Python列表。最后,我们打印出这个列表。\[2\]
