获取“or”之间的多个子字符串

import re

def get_substrings_between(text, start, end):
    pattern = re.compile(f"{start}(.*?){end}")
    substrings = re.findall(pattern, text)
    return substrings

text = "This is a test string. We want to get the substrings between 'or' in this text."
start = "or"
end = "in"

substrings = get_substrings_between(text, start, end)
print(substrings)

['', '']
