My solution should not pass the check
My solution is:
between_markers = lambda a, b, c: a[a.find(b)+1: a.find(c)].lstrip(b) if c in a else a[a.find(b)+1:].lstrip(b)
It is an interminable solution and lack of readability, but I thought it is at least correct. However, after it showed "Task solved" I realized it is not. For example,
between_markers("<head><title>titleMy new site</title></head>", "<title>", "</title>")
will get the result 'My new site' rather than the expected 'titleMy new site'.
Hope you can add some extra checks in order to block such solutions. Thx
