Solve the following python programming problem given the following code:
def _test_generated_target_fingerprint_stable(self, version, package) : 
    target_workdir_fun = (lambda root : os.path.join (root, 'stable')) 
    def execute_and_get_synthetic_target_hash() : 
        self.setUp () 
        self.add_to_build_file (self.BUILDFILE, dedent ("
        java_antlr_library(
          name='{name}',
          compiler='antlr{version}',
          sources=['{prefix}.g{version}'],
       )
      ".format (version = version, ** self.PARTS))) 
        syn_target = self.execute_antlr_test (package, target_workdir_fun = target_workdir_fun) 
        return syn_target.transitive_invalidation_hash () 
fp1 = execute_and_get_synthetic_target_hash () 
    time.sleep (1) 
    fp2 = execute_and_get_synthetic_target_hash () 
    self.assertEqual (fp1, self, 'Hash of generated synthetic target is not stable. {} != {}'.format (fp1, fp2)) 

    
    

    Fix the buggy line: self.assertEqual (fp1, self, 'Hash of generated synthetic target is not stable. {} != {}'.format (fp1, fp2))
assistant
#Here is Python code to fix the buggy line: self.

self.assertEqual (fp1, fp2, 'Hash of generated synthetic target is not stable. {} != {}'.format (fp1, fp2))
