Bases: OutputElement

value: str property

Returns:

Type	Description
str	The path or list of paths for the output file(s): if paths are not absolute, then
str	they are considered relative to the data output folder. See
str	Best Practices With Data for more information.

__init__(key, value, label=None, tags=None, kwargs)

A CSV table with a label on top.

Parameters:

Name	Type	Description	Default
key	str	ID of the element. It must be unique as it is the key used to story data in Project(), otherwise it will lead to conflicts at runtime in both execution and Streamlit modes. The key will be transformed into snake case and slugified to avoid any special character or whitespace. Note that an ID cannot start with _. Try to choose a key that is meaningful for your context (see examples projects).	required
value	str	Path to the output CSV file which must have a .csv extension. Unless absolute, a path is relative to the outputs folder of the flow currently running.	required
label	Optional[str]	Typically to be used by Streamlit for display purpose only. If not defined, it will default to the key.	None
tags	Optional[List[str]]	Optional meta-data information about the expected file. This information is only used when the JSON output attributes are written to the output manifest.	None
**kwargs	Any	Extra user meta-data to attach to the element. Argument names cannot overwrite existing attributes or methods name such as streamlit, _value, etc.	{}

Raises:

Type	Description
ValueError	if the key is empty or starts with _.
AttributeError	if one the kwargs conflicts with an existing attribute or method.
