re escape doesn t double escape  It just looks like it does if you run in the repl  The second layer of escaping is caused by outputting to the screen   When using the repl  try using print to see what is really in the string     python  gt  gt  gt  import re  gt  gt  gt  re escape    stack     overflo  w  arr 1           stack                 overflo    w       arr   1   gt  gt  gt  print re escape    stack     overflo  w  arr 1       stack          overflo  w    arr  1  gt  gt  gt

Simply using re sub might also work instead of str maketrans  And this would also work in python 2 x   gt  gt  gt  print re sub r   -                     lambda m   -    -                                                            m group      stack   overflo w arr 1      stack     overflo  w  arr 1
