[Tutor] How can I make a python script go directory by directory and excecute on files of choice

[Srinivas Iyyer]

Dear group, 
I have Excel files that are arranged according to
transctions under various name/directories.

I found out that all these Excel files are not real
OLE based files and some of them are really tab delim
files with .XLS appended to the end of file name. I
got fooled and started using pyExcelator module. 

Now I want to write a script that can go to each
directory from base directory. 

Say: my dir path is like this:

/home/srini/data/sales
                  - jan05/(1-31).xls
                  - feb05/(1-27).xls 
                  - mar05/(1-31).xls

How can I ask my script residing in data directory to
go to sales and scan all directories and report if
.xls files are really Excel files or text files with
.xls extension. 

could any one please help me here. 

thank you.
