python pandas 对各种文件的读写 IO tools

The pandas I/O API is a set of top level

reader

functions accessed like

pd.read_csv()

that generally return a

pandas

object.


The corresponding

writer

functions are object methods that are accessed like

df.to_csv()

Here is an informal performance comparison for some of these IO methods.
