把倒排引號圍繞使用索引的字符串，python

Question

我在文本文件中有大量的字符串，我想按如下方式在每個字符串周圍放置倒排引號。

文本文件包含這麼多的線路，如：

{created_at：2014年7月7日，文章：土耳其政府已經 繪製的路線圖取締庫爾德工人黨武裝的回報，誰 爲了在土耳其東南部開拓出一個 獨立的國家採取了對土耳其國家武器。}

，我想插入倒報價周圍的日期和文章內容是這樣的...

{created_at：「2014年7月07，」文章：「土耳其政府已經 繪製的取締庫爾德工人黨的武裝分子返回的路線圖誰 爲了開拓拿起武器反對土耳其政府使用蟒蛇指數法在土耳其東南部「}一個 獨立的狀態..

但我得到的結果作爲{created_at : "July 07", 2014, article : "The Turkish government has drawn a roadmap for the return of militants of the banned PKK, who took up arms against the Turkish state in order to carve out a separate state in southeastern Turkey} ..因此它被放置引號錯了位置。

這裏是我的代碼：此粗葉文件的讀/寫你

f = open("textfile.txt", "r") 
for item in f: 
    first_comma_pos = item.find(",") 
    print first_comma_pos 
    first_colon_pos = item.find(" : ") 
    print first_colon_pos 
    second_comma_pos = item.find(",", first_comma_pos) 
    second_colon_pos = item.find(" : ", second_comma_pos) 
    print second_colon_pos 
    item = (item[:first_colon_pos+3] + 
     '"' + item[first_colon_pos+3:second_comma_pos] + '"' + 
     item[second_comma_pos:second_colon_pos+3] + 
     '"' + item[second_colon_pos+3:-1] + '"\n') 
    print item 
    saveFile= open("result.txt", "a") 
    saveFile.write(item) 
    saveFile.write('\n') 
    saveFile.close() 

Answer 1

你是相當準確的，但2個缺陷： -

• 你，你沒有額外增加了指數
• 用於查找第一個逗號本身的位置find你結束"是你{之外。因此，曾經被扔出去的地方

編輯的代碼

f = open("textfile.txt", "r") 
for item in f: 
    first_comma_pos = item.find(",") 
    print item 
    print first_comma_pos 
    first_colon_pos = item.find(" : ") 
    print first_colon_pos 
    second_comma_pos = item.find(",", first_comma_pos+1) # Note change 
    second_colon_pos = item.find(" : ", second_comma_pos) 
    print second_colon_pos 
    item = (item[:first_colon_pos+3] + 
     '"' + item[first_colon_pos+3:second_comma_pos] + '"' + 
     item[second_comma_pos:second_colon_pos+3] + 
     '"' + item[second_colon_pos+3:-2] + '"}\n') # Note change 
    print item 
    saveFile= open("result.txt", "a") 
    saveFile.write(item) 
    saveFile.write('\n') 
    saveFile.close() 

輸出

{created_at： 「2014年7月07，」 文章：「土耳其政府已經繪製的被取締的庫爾德工人黨的武裝分子的路線圖，他們拿起武器對土耳其國家，以便在土耳其東南部劃出一個單獨的州。「}

漂亮哈克但

fix_json.py

import re,json 
s = """{created_at : July 07, 2014, article : The Turkish government has drawn a roadmap for the return of militants of the banned PKK, who took up arms against the Turkish state in order to carve out a separate state in southeastern Turkey.}""" 
parts0 = s.split(":") 
data = {} 
for lhs,rhs in zip(parts0,parts0[1:]): 
    #: assume that the word directly preceding the ":" is the key 
    #: word defined by regex below 
    key = re.sub("[^a-zA-Z_]","",lhs.rsplit(",",1)[-1]) 
    value = rhs.rsplit(",",1)[0] 
    data[key] = value 

print json.dumps(data) 

.. 。以及根據您的示例對您的數據做出一些假設

如果數據始終是格式，可以從右邊記號化的點點滴滴，如：

s = """{created_at : July 07, 2014, article : The Turkish government has drawn a roadmap for the return of militants of the banned PKK, who took up arms against the Turkish state in order to carve out a separate state in southeastern Turkey.}""" 

created_at, a_sep, article_text = s.strip('{}').rpartition('article :') 
start, c_sep, created_date = created_at.rpartition('created_at :') 
new_string = '{{{} "{}", {} "{}"}}'.format(
    c_sep, 
    created_date.strip(' ,'), 
    a_sep, 
    article_text.strip() 
) 

# {created_at : "July 07, 2014", article : "The Turkish government has drawn a roadmap for the return of militants of the banned PKK, who took up arms against the Turkish state in order to carve out a separate state in southeastern Turkey."}
