How to launch python scripts from Windows Shell?

I would like to launch a python script (file.py)

In order to do this I copied the path of this file in the Python interpreter but I get the error SyntaxError: unexpected character after line continuation character

I am beginner and this is the simplest way to launch Python script I found so far... If you have a simpler way I'm open to tips...

Thank you

Here's my Python script: 

import os
import csv

ACCEPTED_MSG="""
Hi {},

We are thrilled to let you know that you are accepted to our 
programming workshop.

Your coach is {}.

Can't wait to see you there ! 

Thank you,

Workshop Organizers
"""

REJECTED_MSG="""
Hi {},

We are verry sorry to let you know that due to a big number
of applications we couldn't fit you at the workshop this time...

We hope to see you next time.

Thank you, 

Workshop Organizers
"""

path_to_file = "C:/Users/Julien/Downloads/data.csv"

file_exists = os.path.exists(path_to_file)

if file_exists:

    csv_file = open(path_to_file)
    csv_reader = csv.reader(csv_file, delimiter=',')
    next(csv_reader)

    for row in csv_reader:
        name, email, accepted, coach, language = row
        print (name, email, accepted, coach, language)

        if accepted =='Yes':
            msg = ACCEPTED_MSG.format(name, coach)
        else:
            msg = REJECTED_MSG.format(name)

            print ("Send e-mail to: {}".format(email))
            print("E-mail content:")
            print (msg)
csv_file.close()

I wasn't able to launch a Python script from the Windows console because I haven't added the variable PATH.

So I added the variable path following this YouTube Tutorial: https://www.youtube.com/watch?v=uXqTw5eO0Mw

Then, I got an error "No such File or directory found" when I was trying to launch the script. That was because I didn't put a SPACE in the path to the script "C: \ ..." instead of "C:\"

Finally, I had a message "python.exe can't find 'main' module". It was because I needed to save my scripts with the ".py" extension once again.

If you just want to run a script then the syntax is (from your system__shell, __not the python shell):

$ python path/to/your/script.py

If you want to execute from within an existing python shell, you can run (in the python shell):

>>> execfile("path/to/your/script.py")

You can run

python<version> <path>

Example:

Python3 test.py

from your error seems like you ran it correctly but the code contains compilation error. Add the code snippet so we can see where is the problem
