假设我有字符串:
string = "this is a test string <LW> I want to <NL>split this string<NL> by each tag I have inserted.<AB>"
我想通过在上一个函数中插入字符串的每个自定义标签分割字符串:
tags = ["<LW>", "<NL>", "<AB>"]
这是所需的输出:
splitString = splitByTags(string, tags)
for s in splitString:
print(s)
输出
"this is a test string <LW>"
" I want to <NL>"
"split this string<NL>"
" by each tag I have inserted.<AB>"
所以基本上我想将字符串分成多个子字符串,同时将这些子字符串保留在拆分中。最快,最有效的方法是什么?我知道我可以使用string.split并将简单的拆分文本追加到每一行,但是我不确定如何使用多个字符串。

将ng test MyOtherModule
与捕获括号一起使用。
例如:
re.split
输出:
import re
string = "this is a test string <LW> I want to <NL>split this string<NL> by each tag I have inserted.<AB>"
tags = ["<LW>", "<NL>", "<AB>"]
splt_str = re.split("(" + "|".join(tags) + ")", string)
for i in range(0, len(splt_str), 2):
print("".join(splt_str[i:i+2]))

以下是如何执行此操作的示例:
import re
def split_string(string, tags):
string_list = []
start = 0
for tag in tags:
tag_index = re.finditer(tag, string)
for item in tag_index:
end_tag = item.start() + len(tag)
string_list.append(string[start:end_tag])
start = end_tag
return string_list
data = split_string(string, tags)
输出:
['this is a test string <LW>', ' I want to <NL>', 'split this string<NL>', ' by each tag I have inserted.<AB>']
