Difficulties with launchd executing python script

Question

I am trying to use launchd to run a python script every 10 minutes. This is easy with cron, but I have been trying for several hours to understand how to operate launchd and I have been unsuccessful. I am using a version of python located in /Users/turtle/bin/. Here is what my launchd file (com.foobar) looks like:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>Label</key>
        <string>com.foobar</string>
        <key>ProgramArguments</key>
        <array>
            <string>/Users/turtle/bin/python</string>
            <string>/Users/turtle/code/baz.py</string>
        </array>
        <key>StartCalendarInterval</key>
        <dict>
            <key>Minute</key>
            <integer>10</integer>
        </dict>
    </dict>
</plist>

When I run:

launchctl load /Library/LaunchAgents/com.foobar

I get:

launchctl: Couldn't stat("/Library/LaunchAgents/com.foobar"): No such file or directory nothing found to load

Can anyone help me? Thanks for your time.

StartCalendarInterval with the key Minute : the script run at the 10th minutes of every hour.

You must use StartInterval : job to be started every N seconds

<key>StartInterval</key>
<integer>600</integer>

launchctl load -w /Library/LaunchAgents/com.foobar

Does that work?

Thanks for the help. Unfortunately, I already tried the -w flag, but it didn't work.

If I add .plist to the file name it now loads, but the python script still doesn't execute.
