用于捕获韩文字母的正则表达式

Question

我的数据框名称如下：

'가락시장(340)',
'가락시장(8)',
'가산디지털단지(7)',
'강남(222)',
'강남구청',
'강동',
'강동구청',
'강변(214)',
'개롱',
'개화산',
'거여',
'건대입구(212)',
'건대입구(7)',
'경복궁(317)',
'경찰병원(341)',
'고덕',
'고려대',
'고속터미널(329)',
'고속터미널(7)',
'공덕(5)',
'공덕(6)',
'공릉',
'광나루',
...

所有列表都在这个link

期望的输出：

가락시장
가산디지털단지
강남
강남구청
강동
강동구청
강변
개롱
개화산
거여
건대입구
경복궁
경찰병원
고덕
고려대
고속터미널
공덕
공릉
광나루

尝试

import re

for i in df['name']:
    i = re.match('^[가-힣]*$', i) # '^[가-힣]&$ is extract Hangeul (Korean alphabet)

但是df['name']没有改变。

如何解决这个问题？

Answer 1

我们也许可以用一个简单的表达式来捕捉你想要的输出，只用一个'作为左边界，然后收集字母，类似于：

'([\p{L}]+)

测试

# coding=utf8
# the above tag defines encoding for this document and is for Python 2.x compatibility

import re

regex = r"'([\p{L}]+)"

test_str = ("'가락시장(340)',\n"
    " '가락시장(8)',\n"
    " '가산디지털단지(7)',\n"
    " '강남(222)',\n"
    " '강남구청',\n"
    " '강동',\n"
    " '강동구청',\n"
    " '강변(214)',\n"
    " '개롱',\n"
    " '개화산',\n"
    " '거여',\n"
    " '건대입구(212)',\n"
    " '건대입구(7)',\n"
    " '경복궁(317)',\n"
    " '경찰병원(341)',\n"
    " '고덕',\n"
    " '고려대',\n"
    " '고속터미널(329)',\n"
    " '고속터미널(7)',\n"
    " '공덕(5)',\n"
    " '공덕(6)',\n"
    " '공릉',\n"
    " '광나루',")

matches = re.finditer(regex, test_str, re.MULTILINE)

for matchNum, match in enumerate(matches, start=1):

    print ("Match {matchNum} was found at {start}-{end}: {match}".format(matchNum = matchNum, start = match.start(), end = match.end(), match = match.group()))

    for groupNum in range(0, len(match.groups())):
        groupNum = groupNum + 1

        print ("Group {groupNum} found at {start}-{end}: {group}".format(groupNum = groupNum, start = match.start(groupNum), end = match.end(groupNum), group = match.group(groupNum)))

# Note: for Python 2.7 compatibility, use ur"" to prefix the regex and u"" to prefix the test string and substitution.

正则表达式

如果不需要此表达式，可以在 regex101.com 中对其进行修改或更改。

Answer 2

您可以使用以下代码删除括号和括号内的字符：

import re
pattern = re.compile(r'\(\w*\)')
for text in YOUR_DATA_LIST : 
    only_station_name = re.sub(pattern, '', text)
    print(only_station_name)
