Python - Delete all files EXCEPT for
<p>I have a Python script and I'm trying to delete all files in this directory EXCEPT for the .csv file.  Getting syntax error on the "not" in this line:</p>

<pre><code>for CleanUp not in glob.glob("c:\python\AIO*.*"):
</code></pre>

<p>If I remove the "not", it will delete the AIO.csv file, but I need to preserve that file and ONLY that file.  Not clear why it's not working.</p>

<pre><code>import os
import glob
import time

file_path = "c:\python\AIO.csv"
while not os.path.exists(file_path):
    time.sleep(10)

if os.path.isfile(file_path):
 #Verifies CSV file was created, then deletes unneeded files.
    for CleanUp not in glob.glob("c:\python\AIO*.*"):
        os.remove(CleanUp)
</code></pre>
