Let's agree that exciting your Python script by double clicking it on a Mac is super cool. It's a way to convinently run your code without opening Terminal going to your folder and typing python code.py then closing it.

It also doesn't look easy when showing it to your friends who aren't into coding.

There are two ways. In fact there are many. Trust me, I have searched everywhere and tried all of them.

The easiest by far, that doesn't include installing Py2app and running into Launching errors is the following:

• Add this standard line at the beginning of your code

  #!/usr/bin/python3
  

  or

  #!/usr/bin/python   #if python3 is the only Python on you computer
  

• Change file name to myPythonCode.command or myPythonCode.tool instead of the normal myPythonCode.py

• Give permission to execute the code by inputing the following code in the terminal to change permission

chmod +x myPythonCode.command

That's basically it. Py2app could work for you with some kinds of Python applications. I personally found this way the quickest and most convenient.
