I am very new to python and I am trying to execute a python file called HelloWorld.Py. The code within the file editor is

#! Python3 print('Hello world!')

I am trying to do this from my windows command line. The correct path from what I can tell in my documents application is C:\Users\china\PythonFiles\HelloWorld.py.

As I am following a Udemy course, it is recommended that you type py.exe C:/Users/china/PythonFiles/HelloWorld.py (filled in with my example).

At first, I returned a syntax error for the use of py.exe. Reading online made me confused about what to put in front of C:, and after removing py.exe, and just typing C:/Users/china/PythonFiles/HelloWorld.py returns the error 'Unable to create process using 'Python3 "C:\Users\china\PythonFiles\HelloWorld.py" '

What am I doing wrong? I have researched online for a few hours and I am still no closer to figuring it out. Please help!

  • Please add your HelloWorld.py file (edit your question), so I can take a look at the code. Seems like there might be a problem with your script. Commented Nov 20, 2020 at 18:13
  • Fixed to include code I wrote in the file. Thank you Commented Nov 20, 2020 at 18:17

Remove the comment, or change it to #!python3. py.exe doesn't like the capitalization.

The comment isn't needed unless you have both Python 2 and Python 3 installed, and it hints to py.exe which Python to use, but requires lowercase python followed by the major and optionally minor version, e.g #!python3.6 or #!python3. If the comment is missing, the latest version of Python installed wiil be used.
