file bug???

[Anand Pillai]

There are many problems with your code.

First of all answer to your main question.

In Line 15, you are using a local variable named 'file'
which is being used to walk a list of files. When you
are using a keyword as a variable, python gets confused
and thinks that you are trying to use a variable before it
is being defined.

If you replace the 'file' in L15 with say 'f', you can use
'file' instead of 'open' in L4.

Some other things.

o 'os' module does not have a function 'walk'. Change it to os.path.walk .
o  os.path.walk takes 3 arguments, not one. You need to correct this.
