running python from cmd.exe

[Dominic Rice]

Hi,

I can't seem to get python to run my scripts using the command: python
<userscript>. py

If I type python the interpreter runs as I sorted out the Path property,

I'm afraid I don't know much about this kind of thing as I'm a science
student who needs some Python not a programmer!

Thanks in advance

Can you be more specific about the error you get?

Say you have a script hw.py that contains one line:
print "Hello Python"

and you run
python hw.py

What is the error you get?

Sure, I get:

can't open file <userscript>.py : [errorno 2]No such file or directory.

Now if I've noticed that if I change directory to (for instance)
\Python25 where the script is the command runs fine.(?)

Oh I just noticed you specified hw.py, in that case just to clarify it
would be can't open file hw.py: [errorno 2]No such file or directory

When you run a script, are you in the directory where the script is
located?

when it works yes! Does it have to be the case then? I assumed that
there was a default folder (eg \Python25) that the python command would
look for the file in, I take it this is not the case then?

The default folder *is* the "current" folder, i.e. "the directory that
you are in". If you want to run a script in another folder, you
specify the path to that script. This is usual in Windows command-line
operation, not special to Python.

By the way, storing your own files in the same folder structure as a
software package (e.g. \Python25) is not a good idea. Keep them
somewhere else e.g. a separate folder for each significantly different
project, a folder for commonly useful stuff, and a junk folder for
mucking about trying things out. Then when e.g. you upgrade to Python
2.6 the possibility of drama is reduced.

HTH,
