Cron job is not executing Python script

I have a script that should run every 30 min every day.

 30 * * * * python /home/pi/MyScript.py

I used every min to test it

 1 * * * * python /home/pi/MyScript.py

but it's not executing, did I used the wrong path? or is the minute not correctly?

You misunderstand the syntax.

In your first example, you tell cron to run MyScript.py at the 30th minute of each hour (ie 10:30), not every 30 minutes.

In the second example, MyScript.py is run at the 1st minute of each hour (ie 10:01), not every minute.

You probably want to do this:

*/30 * * * * python /home/pi/MyScript.py

Now, your script will run every 30 minutes (at 10:00, 10:30, 11:00 etc.). You can change 30 to whatever interval you desire.

If you want to run something every 30 min then the crontab should be something like this 

*/30 * * * * python /home/pi/MyScript.py

Or for every 1 min like this. 

*/1 * * * * python /home/pi/MyScript.py

Your line:

1 * * * * python /home/pi/MyScript.py

will not fire every minute. It will fire every hour when the number of minutes is equal to 1 so 00:01, 01:01, 02:01, etc. In order for the script to fire every minute, you should write:

* * * * * python /home/pi/MyScript.py

and in case you want the script to fire every 30 minutes, you can for instance write:

0,30 * * * * python /home/pi/MyScript.py

Now the script will fire at 00:00, 00:30, 01:00, 01:30, etc.
