这是我的代码：
import re
file = open('file-path.txt','r')
# if there are more than two consecutive blank lines, then we start a new Entry
entries = []
curr = []
prev_blank = False
for line in file:
line = line.rstrip('\n').strip()
if (line == ''):
if prev_blank == True:
# end of the entry, create append the entry
if(len(curr) > 0):
entries.append(curr)
print curr
curr = []
prev_blank = False
else:
prev_blank = True
else:
prev_blank = False
# we need to parse the line
line_list = line.split()
str = ''
start = False
for item in line_list:
if re.match('[a-zA-Z\s]+:.*',item):
if len(str) > 0:
curr.append(str)
str = item
start = True
elif start == True:
str = str + ' ' + item
这是输出：
['number: Jackie Grant', 'Status: Fell Thru Primary closing', 'Acceptance: 01/01/2001 Closing', 'date: 11/11/2011 Property', 'number: Sale', 'price: $200,000', 'Home:', 'Business:', 'Mobile:', 'Home:', 'Business: 555-555-5555', 'Mobile:', 'Home: (575) 222-3455', 'Business:', 'Mobile: (702) 600-3492', 'Home:', 'Business:', 'Mobile: 595-595-5959']
我的问题如下：
除了使用正则表达式挑选密钥，然后抓住后面的文本片段之外，我无法想到更好的方法。
完成后，我想要一个带有键的标题行的csv，我可以将其导入带有read_csv的pandas。我在这个上花了不少时间..
答案 0 :(得分：3)
（这不是一个完整的答案，但评论的时间太长了。）
MLS number）Home: Pager:）: 这意味着您无法通过正则表达式识别字段名。它不可能知道“MLS”是否是先前数据值或后续字段名的一部分。
部分Home: Pager:行指向卖方，部分指向买方或承租人代理或租赁代理。这意味着我在下面采用的天真的逐行方法也不起作用。
这是我正在处理的代码，它针对您的测试数据运行但由于上述原因而输出的输出不正确。这是我参与的方法的参考：
replaces = [
('Closing Report for', 'Report_for:')
,('Report for', 'Report_for:')
,('File number', 'File_number')
,('Primary closing party', 'Primary_closing_party')
,('MLS number', 'MLS_number')
,('Sale Price', 'Sale_Price')
,('Account owner', 'Account_owner')
# ...
# etc.
]
def fix_linemash(data):
# splits many fields on one line into several lines
results = []
mini_collection = []
for token in data.split(' '):
if ':' not in token:
mini_collection.append(token)
else:
results.append(' '.join(mini_collection))
mini_collection = [token]
return [line for line in results if line]
def process_record(data):
# takes a collection of lines
# fixes them, and builds a record dict
record = {}
for old, new in replaces:
data = data.replace(old, new)
for line in fix_linemash(data):
print line
name, value = line.split(':', 1)
record[name.strip()] = value.strip()
return record
records = []
collection = []
blank_flag = False
for line in open('d:/lol.txt'):
# Read through the file collecting lines and
# looking for double blank lines
# every pair of blank lines, process the stored ones and reset
line = line.strip()
if line.startswith('Page '): continue
if line.startswith('Printed on '): continue
if not line and blank_flag: # record finished
records.append( process_record(' '.join(collection)) )
blank_flag = False
collection = []
elif not line: # maybe end of record?
blank_flag = True
else: # false alarm, record continues
blank_flag = False
collection.append(line)
for record in records:
print record
我现在认为对数据进行一些预处理整理步骤会更好一点：
Email: - ＆gt; Seller Email:。然后编写一个记录解析器，它应该很容易 - 检查两个空白行，在第一个冒号处拆分行，使用左位作为字段名称，使用右位作为值。你想要的存储（nb。字典键是无序的）。
答案 1 :(得分：0)
我想通过点击＆＃34; Page＆＃34;来开始新记录会更容易。
只是分享一下我自己的经验 - 编写一个通用的解析器太难了。
鉴于此处的数据，情况并非如此糟糕。不使用简单列表来存储条目，而是使用对象。将所有其他字段作为属性/值添加到对象。
