nltk.toolbox.ToolboxSettings

class nltk.toolbox.ToolboxSettings[source]

Bases: StandardFormat

This class is the base class for settings files.

__init__()[source]
parse(encoding=None, errors='strict', **kwargs)[source]

Return the contents of toolbox settings file with a nested structure.

Parameters

  • encoding (str) – encoding used by settings file

  • errors (str) – Error handling scheme for codec. Same as decode() builtin method.

  • kwargs (dict) – Keyword arguments passed to StandardFormat.fields()

Return type

ElementTree._ElementInterface

close()

Close a previously opened standard format marker file or string.

fields(strip=True, unwrap=True, encoding=None, errors='strict', unicode_fields=None)

Return an iterator that returns the next field in a (marker, value) tuple, where marker and value are unicode strings if an encoding was specified in the fields() method. Otherwise they are non-unicode strings.

Parameters

  • strip (bool) – strip trailing whitespace from the last line of each field

  • unwrap (bool) – Convert newlines in a field to spaces.

  • encoding (str or None) – Name of an encoding to use. If it is specified then the fields() method returns unicode strings rather than non unicode strings.

  • errors (str) – Error handling scheme for codec. Same as the decode() builtin string method.

  • unicode_fields (sequence) – Set of marker names whose values are UTF-8 encoded. Ignored if encoding is None. If the whole file is UTF-8 encoded set encoding='utf8' and leave unicode_fields with its default value of None.

Return type

iter(tuple(str, str))

open(sfm_file)

Open a standard format marker file for sequential reading.

Parameters

sfm_file (str) – name of the standard format marker input file

open_string(s)

Open a standard format marker string for sequential reading.

Parameters

s (str) – string to parse as a standard format marker input file

raw_fields()

Return an iterator that returns the next field in a (marker, value) tuple. Linebreaks and trailing white space are preserved except for the final newline in each field.

Return type

iter(tuple(str, str))
