eelbrain.Datalist

class eelbrain.Datalist(items=None, name=None, fmt='repr')

list subclass for including lists in in a Dataset.

Parameters:

items : sequence

Content for the Datalist.

name : str

Name of the Datalist.

fmt : ‘repr’ | ‘str’ | ‘strlist’

How to format items when converting Datasets to tables (default ‘repr’ uses the normal object representation).

Notes

Modifications:

• adds certain methods that makes indexing behavior more similar to numpy and other data objects
• blocks methods for in place modifications that would change the lists’s length

Examples

Concise string representation:

>>> l = [['a', 'b'], [], ['a']]
>>> print(Datalist(l))
[['a', 'b'], [], ['a']]
>>> print(Datalist(l, fmt='strlist'))
[[a, b], [], [a]]
