how to replace double backslash with one backslash in string...

[Vincent Texier]

Hello,

I want to send 3 chars in hexa code to the serial port.

So I type in a tkinter entry : "\x20\x01\x21"

The string is set in a StringVar().

When I read the stringVar, I get : "\\x20\\x01\\x21"

The length is 12 and not 3 anymore.

How can I replace the escape character from the string with the 
corresponding char, and get my 3 char string back ?

I've tried a re.sub(r'\\', chr(92)) but chr(92) is a double backslash again.


Thanks for any help.
Vince.
