By "neglect" do you mean remove from the output or don't include in the pattern, i.e. find "apple"?
如果是前者：
>>> a.replace('\\', '')
'applec'
如果是后者：
>>> re.search(r'[^\\]*', a)
<re.Match object; span=(0, 5), match='apple'>

If former:
>>> a.replace('\\', '')
'applec'
if latter:
>>> re.search(r'[^\\]*', a)
<re.Match object; span=(0, 5), match='apple'>
