Very basic help needed please - 0621_OWLgale - Nov-28-2016

First time using Python and I bought a book called Python in Easy Steps by Mike McGrath.
I have made it onto page 16!! and 'Writing your first program',
and my first attempt at this is not working,
after creating a hello.py file it says 'to launch command prompt window, navigate to new directory and precisely enter the command python hello.py - to see the Python interpreter run your program', how do you navigate to the directory through the command prompt window? I cannot do this as it does not allow me to go to the directory through the command prompt window and when I enter in the python hello. py, the below is what I get,



C:\Users\gg>C:\Python34\MyScripts>python hello.py
'C:\Python34\MyScripts' is not recognized as an internal or external command,
operable program or batch file.


I will be very grateful if someone can give me advice on how I do this, thanks very much in advance

C:\Users\gg> cd C:\Python34\MyScripts
C:\Python34\MyScripts>python hello.py

OR

C:\Users\gg>python C:\Python34\MyScripts\hello.py

Set up environment Variables Path,
Like in video,but also point to script folder(pip placement),
so for e.g Python 3.4 you add ;C:\python34\;C:\python34\scripts
Restart.
Now should python and pip work from anywhere in cmd.
Test and upgrade pip.
C:\>pip -V
pip 9.0.1 from c:\python34\lib\site-packages (python 3.4)

C:\>cd python34/scripts
C:\Python34\Scripts>pip install --upgrade pip
Requirement already up-to-date: pip in c:\python34\lib\site-packages

thanks for the info snippsat, can this also be done on Windows 10?

RE: Very basic help needed please - snippsat - Nov-28-2016

Works the same in Windows 10.

Obviously that's NOT what I suggested...

Earlier I tried both Python34\MyScripts>python hello.py , and Python34\MyScripts\python hello.py

and both came up with nothing new,

but now I have tried again with Python34\MyScripts\hello.py and it works,

thanks very much buran,

it says in my book to put the word 'python' before 'hello', is that not right?

Also can I please ask you another newbie question, what is the difference between opening up a command prompt window and going through the Start list and clicking Python 3.4 (command line)?

Both are similar, but the command prompt window always has C:\Users\gg> before you can type anything in and the Python 3.4 (command line) has >>>

Many thanks for your time

If you're in the command prompt and just type "python", without a filename, that's what you'll get. It's called the interpreter, or REPL (read eval print loop). It's used mainly for testing short pieces of code, otherwise you should use files and run them.
