`numpy.lib._iotools:StringConverter.update`

source: build-install/usr/lib/python3.14/site-packages/numpy/lib/_iotools.py :766

Signature

   def     update (    self    ,    func    ,    default    =  None   ,    testing_value    =  None   ,    missing_values    =  ''   ,    locked    =  False     )

Summary

Set StringConverter attributes directly.

Parameters

func : function: Conversion function.
default : any, optional: Value to return by default, that is, when the string to be converted is flagged as missing. If not given, StringConverter tries to supply a reasonable default value.
testing_value : str, optional: A string representing a standard input value of the converter. This string is used to help defining a reasonable default value.
missing_values : {sequence of str, None}, optional: Sequence of strings indicating a missing value. If None, then the existing missing_values are cleared. The default is ''.
locked : bool, optional: Whether the StringConverter should be locked to prevent automatic upgrade or not. Default is False.

Notes

update takes the same parameters as the constructor of StringConverter, except that func does not accept a dtype whereas dtype_or_func in the constructor does.
