使用 python 从文本中仅提取指定值
extracting only the specified value from text using python
我有一个包含以下数据的文本文件。我必须提取所有包含 signed
的行
The document was signed on July 12
The document was signed by Charlie
This document was assigned to John
The document was preassigned to Amanda
预期输出：
The document was signed on July 12
The document was signed by Charlie
如果我使用：
for line in file:
if "signed" in line:
print (line)
正在打印所有行
这很容易通过使用单词边界来完成 \b。 \bsigned 将匹配已签名但未分配的内容。
您可以使用re.search(line, ".*\bsigned.*")
