Answer 1

您可以使用split以分号分隔并strip删除任何空格：

>>> s = "test01@testing.com; test02@testing.com; test03#testing1.com"
>>> [(e.strip() + '\n') for e in s.split(';')]
['test01@testing.com\n', 'test02@testing.com\n', 'test03#testing1.com\n']

Answer 2

您可以使用split将地址拆分为多行，strip删除逗号和分号，并join重新排列它们。

>>> s = 'test01@testing.com; test02@testing.com; test03#testing1.com; test04@testing2.com,'
>>> print('\n'.join(m.strip(',;') for m in s.split())))
test01@testing.com
test02@testing.com
test03#testing1.com
test04@testing2.com

Answer 3

如何使用正则表达式：

import re
elist = re.findall(r'([^;,]+)', long_list)
print "".join("\n", elist)

Answer 4

如果您只想将它​​们维护为单个多行字符串，则简单的字符串替换就可以了：

long_list.replace('; ', '\n')

更灵活的解决方案可以使用正则表达式：

import re
re.sub(r'\s+;\s+', '\n')
