我想在Python中将*.sav文件的内容转换为*.csv文件。我编写了以下代码行来访问 *.sav 文件中变量的详细信息。现在，我不清楚如何将访问的变量数据写入带有标题的 .csv 文件
import scipy.io as spio
on2file = 'ON2_2015_112m_220415.sav'
on2data = spio.readsav(on2file, python_dict=True, verbose=True)
以下是我运行上述代码行时的结果：
IDL Save file is compressed
-> expanding to /var/folders/z4/r3844ql123jgkq1ztdr4jxrm0000gn/T/tmpVE_Iz6.sav
