如何在python中高效地根据多个条件拆分文本？

import re

text = "This is a sample text. It contains multiple conditions for splitting."

# 定义多个条件
conditions = [
    r"\bThis\b",  # 单词"This"
    r"\bis\b",  # 单词"is"
    r"\ba\b",  # 单词"a"
    r"\bfor\b"  # 单词"for"
]

# 将多个条件合并为一个正则表达式
pattern = re.compile("|".join(conditions))

# 使用正则表达式拆分文本
result = re.split(pattern, text)

# 输出拆分结果
for i, fragment in enumerate(result):
    print(f"Fragment {i+1}: {fragment.strip()}")

Fragment 1: 
Fragment 2: sample text. It contains multiple conditions
Fragment 3: splitting.
