我正在嘗試將 python dict 字符串寫入（附加）到 Google Sheets下面是我的代碼SCOPES = 'https://www.googleapis.com/auth/spreadsheets.readonly'SPREADSHEET_ID = 'XXX'RANGE_NAME = 'Sheet1!A2:F2'now = time.strftime('%d-%m-%Y %H:%M')def main():    store = file.Storage('token.json')    creds = store.get()    if not creds or creds.invalid:        flow = client.flow_from_clientsecrets('credentials.json', SCOPES)        creds = tools.run_flow(flow, store)    service = build('sheets', 'v4', http=creds.authorize(Http()))    request = service.spreadsheets().values().append(spreadsheetId= SPREADSHEET_ID,                                                 range= RANGE_NAME,                                                 valueInputOption='USER_ENTERED',                                                 insertDataOption='INSERT_ROWS',                                                 body= {now, data2['pagespeed_score'], data2['yslow_score'], Loadedtime, pagesize, data2['page_elements'],})    response = request.execute()    print(response)if __name__ == '__main__':    main()但我收到一個錯誤："TypeError: {2.1982345581054688, '11-09-2018 13:08', 8.836, 109, 52, 55} is not JSON serializable"我認為這些值應該是 json 格式，但我的值是在 python 字典中。
