Définition

class catch_warnings(builtins.object):

help(catch_warnings)

A context manager that copies and restores the warnings filter upon
    exiting the context.

    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.

    If the 'action' argument is not None, the remaining arguments are passed
    to warnings.simplefilter() as if it were called immediately on entering the
    context.
