Let's say I got a string:
F:\\Somefolder [2011 - 2012]\somefile
And I want to use regex to remove everything before: somefile
So the string I get is:
somefile
I tried to look at the regular expression sheet, but i cant seem to get it. Any help is great.
If you want the part to the right of some character, you don't need a regular expression:
f = r"F:\Somefolder [2011 - 2012]\somefile"
print f.rsplit("\\", 1)[-1]
# somefile
不知道你为什么要在这里使用正则表达式...
your_string.rpartition('\\')[-1]
How about this little guy?
[^\\]+$
... in action ...
myStr = "F:\Somefolder [2011 - 2012]\somefile"
result = re.match( r'[^\\]+$', myStr, re.M|re.I)
if result:
print result.group(0)
else:
print "No match!!"

I've got it like you want remove part of string before some point-word ("somefile" in your example)
>> a = 'F:\\Somefolder [2011 - 2012]\somefile'
>> point = 'somefile'
>> print a[a.index(point):]
somefile
from typing import Iterable
def remove_all_before(items: list, border: int) -> Iterable:
return items[items.index(border):] if border in items else items
print(remove_all_before((1,2,3,4,5,6), 3))
