Methods Documentation

convert_np_type(np_type)

For instance, for pandas the "int32" numpy type gets converted to an Int32Dtype() instance to read columns as a nullable int32.

Parameters:

np_typepython:str

The numpy type string to be converted.

Returns:

Any

Corresponding engine-specific type.

get_data_kwargs(header, null_values)

Generate a dictionary of keyword arguments for data parsing.

This accounts for the API variations in each engine CSV reader.

Parameters:
