如何在Jython中搜索字符串中的ASCII字符？

Question

我从使用ASCII字符254作为分隔符的数据库中提取数据.我很难过如何搜索为254返回的字符串然后根据它创建字典？

我的python类

import sys
sys.path.append('C:\\IBM\\UniDK\\uojsdk\\lib\\asjava.jar')
import os.path

from asjava.uniclientlibs import UniDynArray, UniDataSet
from asjava.uniobjects import UniSession, UniFile
from asjava.uniobjects import UniSubroutineException
from asjava.uniobjects.UniObjectsTokens import AT_FM

class u2py :

        def __init__ (self):
            self.conn = UniSession()

        def get_db(self):
            """ establish a connection to Unidata """
            username = 'dbuser'
            password = 'SuperSecretPassword'
            return  self.conn.connect("host", username, password, "ACCOUNT")

        def close_db(self):
            """ drop connection to Unidata """
            if self.conn.isActive():
                self.conn.disconnect()

        def open_file(self,file_name,rec):
            """ open a U2 file read a record and return it """
            uvfile = self.conn.open(file_name)
            uvrec = uvfile.read(rec)
            dataset = uvrec
            uvfile.close()
            return dataset

        def open_field(self,file_name,rec,field):
                    """ open a U2 file read a record and return it """
                    uvfile = self.conn.open(file_name)
                    uvrec = uvfile.readField(rec,field)
                    dataset = uvrec
                    uvfile.close()
                    return dataset

这是控制台中的代码:

from u2py import *

u2 = u2py()
c = u2.get_db() #creates the connection to the DB
c #actually makes the connection
rec = u2.open_file('SOFILE','SO133700')
print rec

然后将其打印到屏幕:

ZZZAA?XN3?CEL?931819501?20020215?BWI/PP??

"■"实际上是字段标记chr(254)

编辑:

我用这个时:

    >>>rec = u2.open_file('SOFILE','SO133699').split(chr(254))

我收到这个错误

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'asjava.uniclientlibs.UniString' object has no attribute 'split'

编辑和最终答案:

使用UniObjects Java

rec.toString().split(chr(254)) 

成功!!!!

Answer 1

your_string.split(chr(254)),例如

>>> "foo\xFEbar\xFEbaz".split(chr(254))
['foo', 'bar', 'baz']

这将返回一个列表.如何建立一个字典,我会留给你,因为我不知道你想要的键和值.
