Windows:
C:\Documents and Settings\M>copy con test.ignore
print("Hello, world!")
^Z
        1 file(s) copied.

C:\Documents and Settings\M>python test.ignore
Hello, world!

Linux:
gideon at gideon:~$ cat >test.ignore
print("Hello, world!")
gideon at gideon:~$ python test.ignore
Hello, world!

Totally sure-fire. Absolutely prevents any execution until it's
renamed. By the way, what does "associate" mean, and what does it have
to do with file names?

gideon at gideon:~$ cat >test.ignore
#!/usr/bin/python
print("Hello, world!")
gideon at gideon:~$ chmod +x test.ignore
gideon at gideon:~$ ./test.ignore
Hello, world!
