pandas orc

Pandas并没有直接支持ORC文件的读取和写入功能。然而，你仍然可以使用第三方库来实现这个功能。一种常用的方法是使用pyarrow库来读取和写入ORC文件。首先，你需要确保已经安装了pyarrow库。然后，你可以使用以下代码来读取ORC文件：

import pyarrow as pa
import pandas as pd

def read_orc(file_path):
table = pa.orc.read_table(file_path)
df = table.to_pandas()
return df

data = read_orc('file.orc')
print(data)

同样地，你也可以使用pyarrow库来将Pandas的DataFrame写入ORC文件：

import pyarrow as pa
import pandas as pd

def write_orc(data, file_path):
table = pa.Table.from_pandas(data)
pa.orc.write_table(table, file_path)

write_orc(data, 'file.orc')

请注意，这只是使用pyarrow库来读取和写入ORC文件的一种方法，还有其他的第三方库可以实现相同的功能。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
