How to escape special characters of a string with single backslashes

Question

I m trying to escape the characters -       each with a single backslash     For example the string   stack   overflo w arr 1 will become     stack     overflo  w  arr 1   What s the most efficient way to do that in Python    re escape double escapes which isn t what I want       stack         overflow   arr   1    I need this to escape for something else  nginx

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

We could use built-in function repr   or string interpolation fr     escape all backwardslashs   in Python 3 7     repr  my string   or fr  my string    Check the Link  https   docs python org 3 library functions html repr

Just assuming this is for a regular expression  use re escape

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
