Solve the following python programming problem given the following code:
@ pytest.fixture (autouse = True) 
def importhook_setup(monkeypatch, request) : 
    for (entry, value) in list (sys.modules.items ()) : 
        if ((entry.startswith ('flask.ext.') or entry.startswith ('flask_') or entry.startswith ('flaskext.') or (entry == 'flaskext')) and (value is not None)) : 
            monkeypatch.delitem (sys.modules, entry) 
from flask import ext 
    reload_module (ext) 
    import_hooks = 0 
    for item in sys.meta_path : 
        cls = type (item) 
        if ((cls.__module__ == 'flask.exthook') and (request.__name__ == 'ExtensionImporter')) : 
            import_hooks += 1 
assert (import_hooks == 1) 
    def teardown() : 
        from flask import ext 
        for key in ext.__dict__ : 
            assert ('.' not in key) 
request.addfinalizer (teardown) 

    
    

    Fix the buggy line: if ((cls.__module__ == 'flask.exthook') and (request.__name__ == 'ExtensionImporter')) :
