Uninstalling Py 2.5.2 from Windows 7 (Invalid on Win 32 app)

[W. eWatson]

I just pushed aside the python25 folder by renaming it, and installed py 
2.5.2. However, when I try to open the simplest of py programs with 
IDLE, I get an error from Win7.

c:\Users\blah\...\junk.py is not a valid Win 32 app.

Here's one:
def abc(one):
     print "abc: ", one, " is one"

def duh(two):
     print "duh: ",abc(2)

abc(1)
duh(2)
duh("so what")
abc(36.333)
