Step 1. Can't figure out how to open hello.py

[Newbie 001]

Opened up cmd, went down to google exercises, could not open hello.py
Found Python27, typed Python in search and opened up python editor.
Now what? "./hello.py" results in invalid syntax error.

Downloaded Notepad++.
It says here " If running hello.py gives the error "Unknown option: -", the file may have the wrong line-ending. Here are the preferences to set for common editors to treat tabs and line-endings correctly for Python:"

But this line here
"Windows Notepad++ -- Tabs: Settings > Preferences > Edit Components > Tab settings, and Settings > Preferences > MISC for auto-indent. Line endings: Format > Convert, set to Unix."

makes zero sense to me whatsoever. Where do I see the option for Line endings, or Format --> Convert??

[Newbie 001]

Also, further confusion.
Why do I even need Notepad++?
I can bring up the python box by typing python in cmd, and I can say open file and open hello.py and edit its code there.

But I can't type in the python box "python hello.py Alice" or "hello.py". This is extremely frustrating.

Can I really not type in
python hello.py
OR
hello.py

in the Python shell???

start => run => cmd

Then type in:

<PATH TO YOUR PYTHON EXECUTABLE> <PATH  TO YOUR PROGRAM>

For example:
C:\Python27\python27.exe C:\Users\YourUserName\Desktop\google-exercises\hello.py

Hi Robert, that didn't work for me.

And is there a way I can just launch hello.py from my Python shell?
I'm able to open Python shell from typing in "python" in my Start > Search

I think I figured out what the problem is:
I have a folder called Joe Smith and the space is throwing the cmd line off. I've tried "Joe Smith", Joe\ Smith, etc but it's not working.

Hi, I've made some progress.

C:\python27\python.exe "C:\users\joesmith\desktop\joe smith\python\google-python-exercises\hello.py"

This works, but i am unable to create this:

C:\google-python-exercises> python hello.py Alice
Hello Alice

as shown on the Python Set Up page:
https://developers.google.com/edu/python/set-up

Also, do I really have to type that all out everytime I wish to run a .py file?
I can launch the Python shell, can't I just run files using that?
I can open using the tab File-->Open-->hello.py that way, but I don't know how I would do hello.py Alice

Not sure if you are still having issues with this but: 

I have a couple of questions: 

1. What output do you get when you type in "python" in the CMS Prompt?

2. What is the output that you get when you type "python hello.py Alice"? 

I would really help if you could paste the complete output here..

I have tried everything to make this work.

The Command Prompt lets me load Python so I can print strings, but I cannot run python hello.py Alice from the Python set up page either. I get invalid syntax errors.

hello what's this

Did you install python properly?

This is because python is not added in your system class path .. from CMD run the command "path" it should see the C:\python27\ in the output if not you need to add it to system class path.
