Description:
 def tolerate(substitute=None, exceptions=None, switch=DEFAULT_TOLERATE_SWITCH):
 """ A function decorator which makes a function fail silently To disable fail silently in a decorated function, specify ``fail_silently=False``. To disable fail silenlty in decorated functions globally, specify ``tolerate.disabled``. Parameters fn : function A function which will be decorated. substitute : function or returning value A function used instead of :attr:`fn` or returning value when :attr:`fn` failed. exceptions : list of exceptions or None A list of exception classes or None. If exceptions is specified, ignore exceptions only listed in this parameter and raise exception if the exception is not listed. switch : string, list/tuple, dict, function or None A switch function which determine whether silent the function failar. The function receive ``*args`` and ``**kwargs`` which will specified to :attr:`fn` and should return status (bool), args, and kwargs. If the function return ``False`` then agggressive decorated function worked as normal function (raise exception when there is exception). Default switch function is generated by :func:`argument_switch_generator` with ``argument_switch_generator('fail_silently')`` so if ``fail_silently=False`` is specified to the function, the function works as noramlly. **From Version 0.1.1**, when switch is specified as non functional value, :func:`argument_switch_generator` will be called with switch as arguments. If string is specified, the switch generator will be called as ``argument_switch_generator(switch)``. If list or tuple is specified, the switch generator will be called as ``argument_switch_generator(*switch)``. If dict is specified, the switch generator will be called as ``argument_switch_generator(**switch)``.
