Question

这是我的清单，

['Query Date                                :September 07, 2017',
 'Address                                    :Aguila arizona',
 'Latitude                                :33.9428069', 'Longitude                                :-113.1740805',
 'Elevation                                :2170.4 Feet',
 'Elevation Limitation:  ASCE 7* Ground Snow **LoadElevation** 3,000 feet: Ground Snow Load is0 ',
 'Elevation > 3,000 and 4,500 feet: Ground Snow Load is5 ',
 'Elevation > 4,500 and 5,400 feet: Ground Snow Load is10 ',
 '']

我想拆分列表中第5个元素的特定单词（即LoadElevation）。因此在加载后它应该被拆分。

输出应该像

['Query Date                                :September 07, 2017',
 'Address                                    :Aguila arizona', 'Latitude                                :33.9428069',
 'Longitude                                :-113.1740805', 'Elevation                                :2170.4 Feet',
 'Elevation Limitation:  ASCE 7* Ground Snow **Load',
 'Elevation** 3,000 feet: Ground Snow Load is0 ', 
 'Elevation > 3,000 and 4,500 feet: Ground Snow Load is5 ',
 'Elevation > 4,500 and 5,400 feet: Ground Snow Load is10 ', 
 '']

伙计们帮助我。提前谢谢。

Answer 1

使用re.findall()函数的简短解决方案：

import re
l = ['Query Date                                :September 07, 2017', 'Address                                    :Aguila arizona', 'Latitude                                :33.9428069', 'Longitude                                :-113.1740805', 'Elevation                                :2170.4 Feet', 'Elevation Limitation:  ASCE 7* Ground Snow LoadElevation 3,000 feet: Ground Snow Load is0 ', 'Elevation > 3,000 and 4,500 feet: Ground Snow Load is5 ', 'Elevation > 4,500 and 5,400 feet: Ground Snow Load is10 ', '']
l[5:6] = re.findall(r'.*\Load|Elevation.*', l[5])

print(l)

输出：

['Query Date                                :September 07, 2017', 'Address                                    :Aguila arizona', 'Latitude                                :33.9428069', 'Longitude                                :-113.1740805', 'Elevation                                :2170.4 Feet', 'Elevation Limitation:  ASCE 7* Ground Snow Load', 'Elevation 3,000 feet: Ground Snow Load is0 ', 'Elevation > 3,000 and 4,500 feet: Ground Snow Load is5 ', 'Elevation > 4,500 and 5,400 feet: Ground Snow Load is10 ', '']

Answer 2

Asumming你的“分裂元素”只出现一次，得到它的索引，切片到那个索引，插入你想要的任何东西，然后添加列表的其余部分。

>>> a = [1, 2, 'SplitHere', 3, 4]
>>> idx = a.index('SplitHere')
>>> a[:idx] + ['Split', 'Here'] + a[idx+1:]
[1, 2, 'Split', 'Here', 3, 4]

我对分割进行了硬编码，因为你没有给出任何分割目标词的规则或标准。

对于通用，您可以尝试以下代码：

import re
for index,line in enumerate(list1):
     if("LoadElevation" in line):
             newList = re.split("LoadElevation",line)
             new_index = index
             list1 = list1[:index]+ [ele + "Load" if index1%2==0 else "Elevation"+ele for index1,ele in enumerate(newList)] + list1[index+1:]

print list1 #['Query Date                                :September 07, 2017', 'Address                                    :Aguila arizona', 'Latitude                                :33.9428069', 'Longitude                                :-113.1740805', 'Elevation                                :2170.4 Feet', 'Elevation Limitation:  ASCE 7* Ground Snow **Load', 'Elevation** 3,000 feet: Ground Snow Load is0 ', 'Elevation > 3,000 and 4,500 feet: Ground Snow Load is5 ', 'Elevation > 4,500 and 5,400 feet: Ground Snow Load is10 ', '']
