# Importing data

The Loader() class is directly callable so a transient call can be made to the class or, for cases where repeated calls are necessary, the Loader() instance can be assigned to a python variable.

The Loader.load() method accepts a string or list of strings to load a single or multiple data sets simultaneously. The paths passed to load() can be any combination of Path objects, file path like string representations, or URIs. A list of Data1D/Data2D objects is returned. An optional format parameter can be passed to specify the expected file extension associated with a reader. If format is passed, it must either be a single value, or a list of values of the same length as the file path list.

To import data using the scripting interface, ensure the python environment is correctly set up and activated.

    (sasdata) $ python
    >>> from sasdata.dataloader.loader import Loader
    >>> loaded_data_sets = Loader().load(path="/path/to/file.ext") # A list of Data objects
    >>> loaded_data_set = loaded_data_sets[0] # The first data object

Please read more on the supported Data Formats.

For more information on the data structure, please see the documentation for Data1D for 1-dimensional data and Data2D for 2-dimensional data.
