saving modules

[Carl]

I downloaded the Python22 software along with the python manual.  In
the manual it says to save the module fibo.py
-I saved the module to c:\python22\fibo.py
- In the DOS mode Directory it reads out as C:\Pyton22
     -The file name reads out as fibopy~1 and the full name reads out
as fibo.py.txt
-The python shell does not recognize this as a module when I try to
import it.
-Please, what do I do now?
