No need to use expensive regex  if barely needed then try- Use r           pattern that is capture  last   and replace with r   i e  blank character    gt  gt  gt re sub r           r     home ro A Python Scripts flask-auto myDirectory scarlett Johanson 1448543562 17 jpg     gt  gt  gt   home ro A Python Scripts flask-auto myDirectory scarlett Johanson 1448543562 17 jpg

The easiest is  as  greggo pointed out  string  mystring   string  -1

The simplest way is to use slice  If x is your string variable then x  -1  will return the string variable without the last character   BTW  x -1  is the last character in the string variable  You are looking for  my file path     home ro A Python Scripts flask-auto myDirectory scarlett Johanson 1448543562 17 jpg   my file path   my file path  -1

Answering the question  to remove the last character  just use string   string  -1    If you want to remove the last     if there is one  or if there is more than one    while string -1             string   string  -1    If it s a path  then use the os path functions   dir    dir1  dir2  file jpg       I m using windows by the way os path dirname dir    although I would  add  a slash in the end to prevent missing the filename in case there s no slash at the end of the original string   dir    dir1  dir2  file jpg  os path dirname dir           When using abspath   if the path isn t absolute I guess   will add the current working directory to the path   os path abspath dir

For a path use os path abspath   import os     print os path abspath my file path

As you say  you don t need to use a regex for this  You can use rstrip   my file path   my file path rstrip        If there is more than one   at the end  this will remove all of them  e g    file jpg    -    file jpg   From your question  I assume that would be ok

To remove the last character  just use a slice  my file path  -1   If you only want to remove a specific set of characters  use my file path rstrip       If you see the string as a file path  the operation is os path dirname  If the path is in fact a filename  I rather wonder where the extra slash came from in the first place

You could use String rstrip   result   string rstrip
