Pythonの正規表現re.findall（）リスト

Question

では、これが私のリストです：

lista=[u'REG_S_3_UMTS_0_0 (RNC)', u'REG_S_3_UMTS_0_1 (RNC)', u'REG_S_3_UMTS_0_2 (RNC)', u'REG_S_2_GSM_NORT_CBSP_bsc_0_0 (BSC)', u'REG_S_2_GSM_NORT_CBSP_bsc_0_1 (BSC)', u'REG_S_2_GSM_NORT_CBSP_bsc_0_2 (BSC)', u'REG_S_3_GSM_ERIC_CBSP_bsc_0_0 (BSC)', u'REG_S_3_GSM_ERIC_CBSP_bsc_0_1 (BSC)', u'REG_S_3_GSM_ERIC_CBSP_bsc_0_2 (BSC)', u'REG_S_3_GSM_HUAP_CBSM_bsc_0_0 (BSC)', u'REG_S_3_GSM_HUAP_CBSM_bsc_0_1 (BSC)', u'REG_S_3_GSM_HUAP_CBSM_bsc_0_2 (BSC)', u'REG_S_3_GSM_HUA_CBSM_bsc_0_0 (BSC)', u'REG_S_3_GSM_HUA_CBSM_bsc_0_1 (BSC)', u'REG_S_3_GSM_HUA_CBSM_bsc_0_2 (BSC)', u'REG_S_3_GSM_IPAC_SABP_bsc_0_0 (BSC)', u'REG_S_3_GSM_IPAC_SABP_bsc_0_1 (BSC)', u'REG_S_3_GSM_IPAC_SABP_bsc_0_2 (BSC)', u'REG_S_3_GSM_NOKI_CLNS_bsc_0_0 (BSC)', u'REG_S_3_GSM_NOKI_CLNS_bsc_0_1 (BSC)', u'REG_S_3_GSM_NOKI_CLNS_bsc_0_2 (BSC)', u'REG_S_3_GSM_NOKI_RFC1_bsc_0_0 (BSC)', u'REG_S_3_GSM_NOKI_RFC1_bsc_0_1 (BSC)', u'REG_S_3_GSM_NOKI_RFC1_bsc_0_2 (BSC)', u'REG_S_3_GSM_NORT_CBSP_bsc_0_0 (BSC)', u'REG_S_3_GSM_NORT_CBSP_bsc_0_1 (BSC)', u'REG_S_3_GSM_NORT_CBSP_bsc_0_2 (BSC)', u'REG_S_3_GSM_SIEM_BSCI_bsc_0_0 (BSC)', u'REG_S_3_GSM_SIEM_BSCI_bsc_0_1 (BSC)', u'REG_S_3_GSM_SIEM_BSCI_bsc_0_2 (BSC)', u'REG_S_GSM_ERIC_CBSP_bsc_0_0 (BSC)', u'REG_S_GSM_ERIC_CBSP_bsc_0_1 (BSC)', u'REG_S_GSM_ERIC_CBSP_bsc_0_2 (BSC)', u'REG_S_GSM_HUAP_CBSM_bsc_0_0 (BSC)', u'REG_S_GSM_HUAP_CBSM_bsc_0_1 (BSC)', u'REG_S_GSM_HUAP_CBSM_bsc_0_2 (BSC)', u'REG_S_GSM_HUA_CBSM_bsc_0_0 (BSC)', u'REG_S_GSM_HUA_CBSM_bsc_0_1 (BSC)', u'REG_S_GSM_HUA_CBSM_bsc_0_2 (BSC)', u'REG_S_GSM_NORT_CBSP_bsc_0_0 (BSC)', u'REG_S_GSM_NORT_CBSP_bsc_0_1 (BSC)', u'REG_S_GSM_NORT_CBSP_bsc_0_2 (BSC)', u'Pool ID: 200'] 

そして、それは私の機能です：私が得る結果

def Filter_List(lista): 

    string = ''.join(lista) 
    match = re.findall(r"\(([A-Z]+)\)|Pool ID", string) 
    return match 

：

[u'RNC', u'RNC', u'RNC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u'BSC', u''] 

最後の要素（プールIDでなければなりません）は表示されません。ただ：u ''だけです。誰かが私の表現をどのように変えるべきか知っていますか？前もって感謝します ！！！

re.findallは、正規表現パターンにキャプチャグループが定義されている場合は、（リストの）タプルを返します。それを削除します。
