如何把Series、DataFrame转换成list
import pandas as pd
>>> df = pd.DataFrame({'a':[1,3,5,7,4,5,6,4,7,8,9],
'b':[3,5,6,2,4,6,7,8,7,8,9]})
>>> df['a'].values.tolist()
[1, 3, 5, 7, 4, 5, 6, 4, 7, 8, 9]
or you can just use
>>> df['a'].tolist()
[1, 3, 5, 7, 4, 5, 6, 4, 7, 8, 9]
To drop duplicates you can do one of the following:
>>> df['a'].drop_duplicates().values.tolist()
[1, 3, 5, 7, 4, 6, 8, 9]
>>> list(set(df['a'])) # as pointed out by EdChum
[1, 3, 4, 5, 6, 7, 8, 9]
# convert df to list[list]
>>> df.values.tolist()
# conver series to list
>>> Series.tolist()
