我目前有这个字符串，我想提取名称，例如，Garet Hayes、Ronald Allen 等。

Executives
Garet Hayes - Director, Public Relations
Ronald Allen - Chief Executive Officer
Gilbert Danielson - Executive Vice President and Chief Financial Officer
Steven Michaels - President
John Robinson - Executive Vice President and President and Chief Executive Officer, Progressive Finance Holdings LLC

我可以通过以下代码提取名字 Garet Hayes：

def partiesExtractor(doc):
    executives = []
    executives.append(doc[doc.lower().index('executives') + len('executives') + 1 : doc.index(' -')])
    return executives

但我觉得应该有一种更有效的方法，即使只是得到第一个名字，更不用说第二个或列表的其余部分了。我该怎么做？

您需要将内容分成几行，然后在破折号上拆分每个内容，并保留第一部分

def partiesExtractor(doc):
    executives = []
    for line in doc.splitlines()[1:]:
        executives.append(line.split("-")[0].strip())
    return executives
    # return [line.split("-")[0].strip() for line in doc.splitlines()[1:]] # list-comprenhension


text = """Executives
Garet Hayes - Director, Public Relations
Ronald Allen - Chief Executive Officer
Gilbert Danielson - Executive Vice President and Chief Financial Officer
Steven Michaels - President
John Robinson - Executive Vice President and President and Chief Executive 
Officer, Progressive Finance Holdings LLC"""

print(partiesExtractor(text))  # ['Garet Hayes', 'Ronald Allen', 'Gilbert Danielson', 'Steven Michaels', 'John Robinson']

regex你也可以使用

def partiesExtractor(doc):
    return re.findall("^[A-Z][a-z]+ [A-Z][a-z]+", doc, flags=re.MULTILINE)

与@azro 使用列表理解类似的解决方案：

def partiesExtractor(doc):
  return [line.split(" - ")[0] for line in doc.split("\n")[1:]]

使用正则表达式：


import re

s = '''Executives
Garet Hayes - Director, Public Relations
Ronald Allen - Chief Executive Officer
Gilbert Danielson - Executive Vice President and Chief Financial Officer
Steven Michaels - President
John Robinson - Executive Vice President and President and Chief Executive Officer, Progressive Finance Holdings LLC'''

reg = '(\w+\s\w+)\s-\s'

names = re.findall(reg,s)
print(names)


['Garet Hayes', 'Ronald Allen', 'Gilbert Danielson', 'Steven Michaels', 'John Robinson']
