Automating and updating EA from python.

If I have an EA (MyEa.ex5) and a set file (Params.set). Can I use a python script to automatically start the EA, read the results when done, update the .set file and repeat the process?

You could, but you would effectively just be "shelling" out the process of starting MetaTrader from the command-line with the required configuration, so you might as well use a command batch file instead which then calls a python script to process the set file. Read the documentation on how to start MetaTrader from the command line.

Learn how to design can i call "backtest" Is there a tester

Thank you very much, but once the EA has finished and python has finished analyzing the results and updating the .set file then I wouldn't I need python to start the EA again? 

n't

Your question makes no sense. As I have already explained, a pure python script, cannot directly start an EA on MetaTrader. You can only do it via the command-line (or by "shelling" from python) as described in the documentation I linked for you. Did you read it?

Without "shelling" you can't do it! That is why I stated that it will be easier to do it from a command batch file instead.
