filterwarnings

Synopsis

filterwarnings(action,message='.*',category=Warning,
               module='.*',lineno=0, append=False)

Adds a filter to the list of active filters. When append is true, filterwarnings adds the filter after all other existing filters (i.e., appends the filter to the list of existing filters); otherwise filterwarnings inserts the filter before any other existing filter. All components, save action, have default values meaning match everything. As detailed above, message and module are pattern strings for regular expressions, category is some subclass of Warning, lineno is an integer, and action is a string that determines what happens when a message matches this filter.
