将 <suds.sax.text.Text> 对象转换为字符串？

问题描述

我的数据框中有一列 suds.sax.text.Text 类型，我想将其转换为字符串。除了这个site，我找不到太多关于如何做到这一点的信息。使用 pandas.DataFrame.astype 不起作用。我相信有一种简单的方法可以做到这一点。文档只是在我头上。我正在使用 Web 服务来使用其某些功能来返回有关气象站的一些元数据。此元数据作为 suds 对象返回。到网络服务的链接是 here.

from suds.client import Client
from suds.transport.https import HttpAuthenticated
from urllib.error import URLError
from urllib.request import HTTPSHandler
import ssl
import pandas as pd

ssl._create_default_https_context = ssl._create_unverified_context
_URL_AWDB_WSDL = 'https://www.wcc.nrcs.usda.gov/awdbWebService/services?WSDL'

def _execute_awdb_call(a_func,ntries_max=3,sleep_sec=5,**kwargs):

    ntries = 0

    while 1:

        try:

            a_result = a_func(**kwargs)
            break

        except Exception as e:
            ntries += 1

            if ntries == ntries_max:

                raise

            else:

                print(("WARNING: Received error executing AWDB function %s:"
                       " %s. Sleeping %d seconds and trying again." % 
                       (str(a_func.method.name),str(e),sleep_sec)))

                sleep(sleep_sec)

    return a_result

def _stationMetadata_to_tuple(a_meta):

        list_meta = [None] * len(_stnmeta_attrs)

        for i,a_attr in enumerate(_stnmeta_attrs):

            try:
                list_meta[i] = a_meta[a_attr]
            except AttributeError:
                # Doesn't have attribute
                continue

        return tuple(list_meta)







try:
    _client = Client(_URL_AWDB_WSDL)
    _stnmeta_attrs = (_client.factory.
                          create('stationMetaData').__keylist__)
except URLError as e:
    if type(e.reason) == ssl.SSLError:
        print("Warning: SSL Error connecting to AWDB web service. Skipping verification...")
        _client = Client(_URL_AWDB_WSDL,transport=_CustomTransport())
        _stnmeta_attrs = (_client.factory.
                          create('stationMetaData').__keylist__)
    else:
        raise

stn_triplets = ['878:WY:SNTL','1033:CO:SNTL']

stn_metas = _execute_awdb_call(_client.service.
                                     getStationMetadataMultiple,stationTriplets=stn_triplets)

stn_tups = [_stationMetadata_to_tuple(a) for a in stn_metas]

df_stns = pd.DataFrame(stn_tups,columns=_stnmeta_attrs)

stns = df_stns.rename(columns={'actonId': 'station_id','name': 'station_name'})

stns['station_id'] = stns.station_id.fillna(stns.stationTriplet)

stns = stns[~stns.station_id.isnull()]
print(type(stns.beginDate[0]))
