Solve the following python programming problem given the following code:
def __put_get_test(self, operation) : 
    curdir = os.path.abspath (os.path.curdir) 
    try : 
        test_path = os.path.join (os.path.dirname (os.path.abspath (__file__)), 'test_scripts', 'some_files') 
        contents = self.__get_directory_contents (test_path) 
        contents.remove (os.path.join ('some_files', 'dir_2', 'dir_3', 'dir_4', 'private.txt')) 
        test_shas = self.__get_directory_sha256 (test_path) 
        del test_shas [os.path.join ('some_files', 'dir_2', 'dir_3', 'dir_4', 'private.txt')] 
        def dest_assert(client_out, destdir) : 
            if (operation == 'put') : 
                self.assertEqual (sorted (client_out.splitlines ()), contents) 
dest_contents = self.__get_directory_contents (os.path.join (destdir, 'some_files')) 
            self.assertEqual (contents, dest_contents) 
            self.assertEqual (test_shas, self.__get_directory_sha256 (os.path.join (destdir, 'some_files'))) 
with tempfile.TemporaryDirectory (suffix = ' spaces in name') as tempdir : 
            os.chdir (tempdir) 
            with tempfile.TemporaryDirectory () as destdir : 
                try : 
                    (cb, client_cmd) = self.get_curlbomb ('{operation} --exclude="private.txt" {source} {dest}'.format (operation = operation, source = test_path, dest = destdir)) 
                    (client_out, client_err) = self.run_client (curdir) 
                    cb.join () 
                    dest_assert (client_out, destdir) 
finally : 
                    pass 
with tempfile.TemporaryDirectory (suffix = ' spaces in name') as tmpdir : 
            os.chdir (tmpdir) 
            (cb, client_cmd) = self.get_curlbomb ('{operation} --exclude="private.txt" {source}'.format (operation = operation, source = test_path)) 
            (client_out, client_err) = self.run_client (client_cmd) 
            cb.join () 
            dest_assert (client_out, tmpdir) 
finally : 
        os.chdir (curdir) 

    
    

    Fix the buggy line: (client_out, client_err) = self.run_client (curdir)

#Here is Python program to fix the buggy line: (client_out, client_err) = self.

(client_out, client_err) = self.run_client (client_cmd)
