如何从列表列表中创建 Pandas DataFrame？

Question

我有一个列表列表。这是它的一个示例。

[[], ['1', 'Anthony Taylor', '6', '11.17', '0.68', '0.17', '1.83', '11', '0.17', '1'], ['2', 'Jonathan Moss', '4', '12.75', '0.73', '0.00', '2.00', '8', '0.00', '0'], ['3', 'Martin Atkinson', '3', '11.00', '0.69', '0.67', '1.67', '5', '0.00', '0'], ['4', 'Graham Scott', '3', '10.00', '0.67', '0.00', '0.33', '1', '0.00', '0'], ['5', 'Chris Kavanagh', '3', '10.33', '0.74', '0.00', '1.67', '5', '0.00', '0'], ['6', 'Michael Oliver', '2', '12.00', '0.62', '1.00', '2.00', '4', '0.00', '0'], ['7', 'Paul Tierney', '2', '12.50', '0.66', '0.00', '2.50', '5', '0.00', '0'], ['8', 'Mike Dean', '2', '14.50', '0.73', '0.50', '3.00', '6', '0.00', '0'], ['9', 'Andre Marriner', '2', '8.50', '0.53', '0.00', '2.00', '4', '0.00', '0'], ['10', 'Kevin Friend', '2', '9.50', '0.50', '0.00', '3.00', '6', '0.00', '0'], ['11', 'Craig Pawson', '1', '9.00', '0.45', '0.00', '1.00', '1', '0.00', '0'], ['12', 'Stuart Attwell', '1', '9.00', '0.75', '0.00', '2.00', '2', '0.00', '0'], ['13', 'Lee Probert', '1', '11.00', '0.73', '0.00', '0.00', '0', '0.00', '0'], ['', 'Total / Average', '32', '11.09', '0.66', '0.19', '1.81', '58', '0.03', '1']]

我如何创建一个类似于这种格式的 Pandas DataFrame（每一行都有一个单独的名称）？

['1', 'Anthony Taylor', '6', '11.17', '0.68', '0.17', '1.83', '11', '0.17', '1']
['2', 'Jonathan Moss', '4', '12.75', '0.73', '0.00', '2.00', '8', '0.00', '0']
['3', 'Martin Atkinson', '3', '11.00', '0.69', '0.67', '1.67', '5', '0.00', '0']
['4', 'Graham Scott', '3', '10.00', '0.67', '0.00', '0.33', '1', '0.00', '0']
['5', 'Chris Kavanagh', '3', '10.33', '0.74', '0.00', '1.67', '5', '0.00', '0']
['6', 'Michael Oliver', '2', '12.00', '0.62', '1.00', '2.00', '4', '0.00', '0']
['7', 'Paul Tierney', '2', '12.50', '0.66', '0.00', '2.50', '5', '0.00', '0']
['8', 'Mike Dean', '2', '14.50', '0.73', '0.50', '3.00', '6', '0.00', '0']
['9', 'Andre Marriner', '2', '8.50', '0.53', '0.00', '2.00', '4', '0.00', '0']
['10', 'Kevin Friend', '2', '9.50', '0.50', '0.00', '3.00', '6', '0.00', '0']
['11', 'Craig Pawson', '1', '9.00', '0.45', '0.00', '1.00', '1', '0.00', '0']
['12', 'Stuart Attwell', '1', '9.00', '0.75', '0.00', '2.00', '2', '0.00', '0']
['13', 'Lee Probert', '1', '11.00', '0.73', '0.00', '0.00', '0', '0.00', '0']
['', 'Total / Average', '32', '11.09', '0.66', '0.19', '1.81', '58', '0.03', '1']

在我的研究过程中，this 的回答对我有所帮助，但它仍然只将所有内容放在一个列中，而我希望为特定列表的每个元素设置一个单独的列。 有没有办法做到这一点？

Answer 1

您可以过滤掉第一个子列表并传递给 DataFrame 构造函数，也可以通过另一个列表设置列名：

L = [[], ['1', 'Anthony Taylor', '6', '11.17', '0.68', '0.17', '1.83', '11', '0.17', '1'], ['2', 'Jonathan Moss', '4', '12.75', '0.73', '0.00', '2.00', '8', '0.00', '0'], ['3', 'Martin Atkinson', '3', '11.00', '0.69', '0.67', '1.67', '5', '0.00', '0'], ['4', 'Graham Scott', '3', '10.00', '0.67', '0.00', '0.33', '1', '0.00', '0'], ['5', 'Chris Kavanagh', '3', '10.33', '0.74', '0.00', '1.67', '5', '0.00', '0'], ['6', 'Michael Oliver', '2', '12.00', '0.62', '1.00', '2.00', '4', '0.00', '0'], ['7', 'Paul Tierney', '2', '12.50', '0.66', '0.00', '2.50', '5', '0.00', '0'], ['8', 'Mike Dean', '2', '14.50', '0.73', '0.50', '3.00', '6', '0.00', '0'], ['9', 'Andre Marriner', '2', '8.50', '0.53', '0.00', '2.00', '4', '0.00', '0'], ['10', 'Kevin Friend', '2', '9.50', '0.50', '0.00', '3.00', '6', '0.00', '0'], ['11', 'Craig Pawson', '1', '9.00', '0.45', '0.00', '1.00', '1', '0.00', '0'], ['12', 'Stuart Attwell', '1', '9.00', '0.75', '0.00', '2.00', '2', '0.00', '0'], ['13', 'Lee Probert', '1', '11.00', '0.73', '0.00', '0.00', '0', '0.00', '0'], ['', 'Total / Average', '32', '11.09', '0.66', '0.19', '1.81', '58', '0.03', '1']]

Answer 2

使用pandas.DataFrame.from_records:

import pandas as pd

df = pd.DataFrame.from_records(x[1:]))
print(df)

输出：
