pandas.api.extensions.ExtensionArray._from_sequence_of_strings#

classmethod ExtensionArray._from_sequence_of_strings(strings, *, dtype, copy=False)[source]#

Construct a new ExtensionArray from a sequence of strings.

Parameters:

stringsSequence: Each element will be an instance of the scalar type for this array, cls.dtype.type.
dtypeExtensionDtype: Construct for this particular dtype. This should be a Dtype compatible with the ExtensionArray.
copybool, default False: If True, copy the underlying data.

Returns:

ExtensionArray
