mwptoolkit.utils.preprocess_tool.number_operator

mwptoolkit.utils.preprocess_tool.number_operator.constant_number(const)[source]

Converts number to constant symbol string (e.g. ‘C_3’). To avoid sympy’s automatic simplification of operation over constants.

Parameters

const (Union[str,int,float,Expr]) – constant value to be converted.

Returns

(str) Constant symbol string represents given constant.

Parameters

  • sentence_list (list) – list of words.

  • fraction_acc (int|None) – the accuracy to transfer fraction to float, if None, not to match fraction expression.

Returns

transfered sentence.

Return type

(list)
