Your string doesn't contain what you think it does. Do a
"print path". Hint: the string "\01" consists of a single byte
who's value is 001 base 8.

Notice that the string in the error message contains \x01?
That's the byte that got changed.

Right.

I don't understand the part about the path variable.
The backslash character is used in both C and Python as an
escape character so that you can encode special values in
string literals. For example: '\r' is a carriage return '\n'
is a linefeed, \0nnn is a single byte with the octal value nnn,
and so on.
Microsoft's choice of '\' as a path separator was a terribly
bad one (one of many made by Microsoft over the years). Most
Windows system calls will accept forward slashes, so the
easiest thing to do is usually just type the strings with
forward slashes.
