Question

I know it’s simple, but I want a nice method. How from url string like:

/en/something/123/foo/

get

/something/123/foo/

?

It means, I want to remove first level (prefix).

Answer 1

If it’s always three characters long:

str = str[3:]

If it can be variable-length, using only string/list operations:

str = '/' + '/'.join( str.split('/')[2:] )

Or using regex:

import re
str = re.sub('^/[a-z]*', '', str)

I would probably use the last method. If you need to do this a lot (e.g. in a loop), consider compiling the regex using re.compile() to speed it up.
