我是python编程的新手，并且一直在使用它来尝试改进我工作中的一些繁琐的任务。一个这样的任务是采用由软件输出的特定格式的报告，并将其转换为另一软件可读取的格式以供进一步处理。
到目前为止，通过使用我在此处研究堆栈溢出和其他各种资源所能找到的内容，我做得相当不错。但我已经遇到了一个我没有太多运气破解并希望得到一些建议或指向正确方向的那个。
我的原始数据是这样的：
BR6.FLD T: Tue Nov 07 15:22:25 2017
//

......根据现场观察的数量，持续很长时间。
通过一系列列表推导，我已经通过这个来输出一个更友好的文件，如下所示：
Station:
CH9583R TT Ht: 1.4240
Measurement:
H: 20-24-28 V: 92-44- 9 S: 115.9559

下一步是我想将其转换为json对象，以便我可以访问某些代码中的属性来输出最终形式。
目前我能输出的是：

以json的形式阅读这个不太正确。我的主要问题是我不确定如何解决为插入点搜索字符串的问题。我想说的是：
if a_sequence_of_characters is_followed_by(another_sequence):
insert(',',location)
并使用它来完成格式化数据。
对不起帖子的长度。欢迎提出任何建议，并提前感谢您的帮助。
答案 0 :(得分：0)
我可能对您的数据有足够的了解，以避免对.fld文件如何转换为.dat文件的一些猜测。如果我对此有任何接近，我想知道直接从前者到后者是否更容易。
这是我到目前为止所拥有的。
import re
coords_line = re.compile(
r'Coordinate:\s+Name:\s+(?P<name>[a-z0-9]+)[^X]+X:\s+(?P<X>[0-9.]+)[^Y]+Y:\s+(?P<Y>[0-9.]+)[^Z]+Z:\s+(?P<Z>[0-9.]+)', re.I)
measurement_line = re.compile(
r'''Measurement:\s+H:\s+(?P<h_degrees>[0-9]+).\s+(?P<h_minutes>[0-9]+)'\s+(?P<h_seconds>[0-9]+)"\s+V:\s+(?P<v_degrees>[0-9]+).\s+(?P<v_minutes>[0-9]+)'\s+(?P<v_seconds>[0-9]+)"\s+S:\s+(?P<S>[0-9.]+)''')
attributes_line = re.compile(
r'''Attribute: Text Attribute for Vertex:\s+N:store_pt_string_name\s+V:(?P<attribute>[a-z0-9]+)''', re.I)
with open('greg_out.txt', 'w') as greg_out:
coords_info = []
with open('greg_in.txt') as greg:
for line in greg:
m = coords_line.search(line)
if m:
if not m.group('name') in coords_info:
coords_info.append(m.group('name'))
print ('C', m.group('name'), m.group('X'), m.group('Y'), m.group('Z'), file=greg_out)
print (file=greg_out)
current_coords = None
with open('greg_in.txt') as greg:
for line in greg:
m = coords_line.search(line)
if m:
if current_coords :
print ('DE\n', file=greg_out)
current_coords = m.group('name')
print ('DB', m.group('name'), file=greg_out)
m = measurement_line.search(line)
if m:
recent_horizontal = (m.group('h_degrees'), m.group('h_minutes'), m.group('h_seconds'), m.group('S'), m.group('v_degrees'), m.group('v_minutes'), m.group('v_seconds'))
m = attributes_line.search (line)
if m:
attribute = m.group('attribute')
if attribute[0] in '0123456789':
attribute = 'CH' + attribute
print ('DM', attribute, '{}-{}-{} {} {}-{}-{}'.format(*recent_horizontal), file=greg_out)
print ('DE\n', file=greg_out)
这就是它产生的东西。

有些项目显然是缺失的，大多数情况下是因为我不知道它们是如何计算的，也不想为此付出努力。
