Eval() doesn't seem to recognize the r'string' format. Is there a way
around this.
Example:
If I input: ---------eval("r'C:\tkll l\ndfd\bll'")
I get the output:
Traceback (most recent call last):
File "<pyshell#3 >", line 1, in <module>
eval("r'C:\tkll l\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

The r'' format is purely for the interpreter; eval wouldn't know the
difference.
Your problem is that eval and exec evaluate source. You're trying to
do execfile().

The string you are passing to eval already contains that newline. Use a raw
string instead:
>>eval(r"r'C:\t klll\ndfd\bll'" )
'C:\\tklll\\ndf d\\bll'

This is not a raw string: "r'\tsometh ing in quotes'". It is a string
starting with an "r", a "'", a tab, and and "s".
This is a raw string: r'\tsomething in quotes'. It is a string
starting with a "\", a "t" and an "s".
Notice that the \t and \n in c:\tkllll\ndfd\ bll were treated like tab
and newline? Try eval(r'c:\tklll l\ndfd\bll')
(You will get a different error now, but it wont be a raw string
problem.)

The \n is being converted to a newline before the string is passed to eval.
Try eval(r"r'C:\tkl ll\ndfd\bll'")
