Question

我一直在处理一个问题，我需要将大量的Mac文件和文件夹存档，并需要将它们存档在Windows服务器数据磁带上。当我到达.DS_store文件和其他mac字符时，会出现问题和挂断。所以我需要在移动到windows之前基本上做一个清理步骤。还有一件事就是寻找像子弹字符这样的非拉丁字符，然后删除它们或用_（下划线字符）替换它们。我无法让它工作。
跑步时抱怨压痕，而我的任何操纵都没有结果。处理非拉丁字符的代码区域是否正常？任何帮助将不胜感激。

如果你的意思是拉丁字符而不是ASCII，那么regex就是你的朋友：

s = u'汉语 / 漢語; Hànyǔ or 中文; Zhōngwén.tmp'

> print regex.sub(u'\p{^Latin}', u'_', s)
_________Hànyǔ_or_____Zhōngwén_tmp

> print regex.sub(u'\p{^Latin}+', u'_', s)
_Hànyǔ_or_Zhōngwén_tmp

> print '.'.join( regex.sub(u'\p{^Latin}+', u'_', t)
                  for t in s.rsplit('.', 1) )
_Hànyǔ_or_Zhōngwén.tmp

如果你想保留被替换的角色：

> print '.'.join( regex.subf(u'\p{^Latin}',
                             lambda m: '_%04x' % ord(m[0]),
                             t)
                  for t in s.rsplit('.', 1) )

可逆：

regex.subf('_([0-9a-f]{4})', lambda m: unichr(int(m[1], 16)), s)

Answer 2

试试这个：

p = re.compile(r'[^A-Za-z0-9]')
filename = p.sub('_', filename)

例如：

>>> p.sub('_', 'this-is-it')
'this_is_it'
>>> p.sub('_', 'â ê bla bla bla')
'______bla_bla_bla'

Answer 3

safe_fname = 'â ê bla bla bla'.encode("ascii","ignore")

（假设你的意思是ascii ...而不是拉丁语）
