Eval and raw string ??

[Mark]

Eval() doesn't seem to recognize the r'string' format. Is there a way
around this.
Example:
If I input: ---------> eval("r'C:\tklll\ndfd\bll'")
I get the output:

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    eval("r'C:\tklll\ndfd\bll'")
  File "<string>", line 1
    r'C:	klll
       	    ^
SyntaxError: EOL while scanning single-quoted string

The same principle applies for exec.

Thanks in advance,
Mark
