从zipfile中读取sas7bdat作为熊猫数据框

Question

我有一个名为myfile.zip的zip文件，其中包含文件mysasfile.sas7bdat，我想将其作为熊猫数据框读取。我已经尝试了一些无效的方法，但这是我目前的方法：

import zipfile

zipfile = zipfile.ZipFile('myfile.zip', 'r')
sasfile = zipfile.open('mysasfile.sas7bdat')

df = pd.read_sas(sasfile)

错误：

---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
<ipython-input-82-6d55436287b5> in <module>()
      3 imgfile = archive.open('curated_dataset_preview.sas7bdat')
      4 
----> 5 df = pd.read_sas(imgfile)

/opt/python/python35/lib/python3.5/site-packages/pandas/io/sas/sasreader.py in read_sas(filepath_or_buffer, format, index, encoding, chunksize, iterator)
     38         filepath_or_buffer = _stringify_path(filepath_or_buffer)
     39         if not isinstance(filepath_or_buffer, compat.string_types):
---> 40             raise ValueError(buffer_error_msg)
     41         try:
     42             fname = filepath_or_buffer.lower()

ValueError: If this is a buffer object rather than a string name, you must specify a format string

Answer 1

您缺少参数format

import zipfile

zipfile = zipfile.ZipFile('myfile.zip', 'r')
sasfile = zipfile.open('mysasfile.sas7bdat')

df = pd.read_sas(sasfile, format='sas7bdat')
