python中从字符串中截取中文和英文字符

# -*- coding: utf-8 -*-
#encoding=utf8
import os,sys,re
#
# test_str1="蒙派克E"
#
# test_str2="新ABC蒙派克"
#
# test_s1 = test_str1.decode("utf-8")
# test_s2= test_str2.decode("utf-8")
#
# pat_1 = re.compile(ur"[u4e00-u9fa5]") ＃这里是关键，
#
# s1_zhongwen=""
#
# s2_zhongwen=""
#
# for item in re.findall(pat_1,test_s1): ＃这里截取出中文字符
#     # print item
#     s1_zhongwen=s1_zhongwen+item
#     print s1_zhongwen
#
# for item in re.findall(pat_1,test_s2):
#     s2_zhongwen=s2_zhongwen+item
#     print s2_zhongwen
#
# for item in (set(s1_zhongwen)-set(s2_zhongwen))|(set(s2_zhongwen)-set(s1_zhongwen)):
#     print item
 #计算到两个车型的中文名称的重叠度。
 # print pat_1.split(test_s2)＃这里截取出非中文的字符 


以及，快速的把字符串，变成各个单个字符元素组成的集合的方法

# tl1=[1,3,5,"abc"]
#
# tl2=[3,4,5]
#
# tl3=[5,9]
#
#
#
# test_set=set(tl1) | set(tl2) | set(tl3)
#
