The 'record' argument specifies whether warnings should be captured by a custom implementation of warnings.showwarning() and be appended to a list returned by the context manager. Otherwise None is returned by the context manager. The objects appended to the list are arguments whose attributes mirror the arguments to showwarning(). The 'module' argument is to specify an alternative module to the module named 'warnings' and imported under that name. This argument is only useful when testing the warnings module itself. FN)�recordr< c C s( || _ |du rtjd n|| _d| _dS )z�Specify whether to record warnings and if an alternative module should be used other than sys.modules['warnings'].
