I'm brand new to using/playing with Python, and I have what is likely aPython is fun and it's easier to use a real OS to develop the programs,
very simple question but can't seem to figure it out.
then if need be, not that difficult to move them to windows:)
I wrote up a script in my preferred text editor. It contains maybe ten
lines of code. I want to be able to execute those code lines with a
single command either from the inline mode or from IDLE. How do I do
this? I saved the file (myscript.py) in a folder that I've specified
in my PYTHONPATH environment variable, and when I type
If you are going to use a text editor to do python with, may I suggest
gVim, or vim it will take care of ALOT of syntax errors dure to
indentation for you. Grant it I am a command line junky, but still...
Ok, the above seems to me like you are useing windows. If so, the chmod
import myscript
the script runs. If, later during the same session, I type
myscript
all I get for output is
<module 'myscript' from 'c:\documents and settings\t_crane\my
documents\Python Modules\myscript.pyc'>
Somwhere in the beginning tutorial there's this line:
"The script can be given a executable mode, or permission, using the
chmod command:
$ chmod +x myscript.py"
commands are going to be just about worthless. If you install unix
services for windows, you will get some functionality, but not also, and
still what's the point. Linux is free and much more stable, secure,
etc...
Which I took to mean that if I enter that I would be able to do what IOK, excuseing my editorial comments above, here is what I see and
wanted. But no, it just highlights 'myscript' in red and says it's a
syntax error.
What am I missing?
correct me if I'm wrong.
1) you use windows
2) You have not been around any OS other than windows
and I mean this as no insult, just making sure I understand you. The
answer to your questions are as follows. In Unix/Linux/XXix/Solaris and
most anyother unixy(yes that's a word, I just made it up) OS you can add
the first line of the script being something like
#!/usr/bin/python
or where ever you installed python to, then FROM A COMMAND LINE run
chmod <perms> <file name and path>
and it will make the script executable. What happens is when you tell
the script to run, it looks at the line and then knows where to pull the
inter. from. the # just comments it out so it don't try to run it with
the rest of the script, the ! tells the computer to pay attention to it.
As far as I know, you cannot do this in Windows. to run it in a single
command, you would have to either compile it with py2exe which will give
you the .exe and a dll or two or you can simple make a batch file that
would look something like
@ECHO OFF
<path to python>python <path to script>script.py
the @ECHO OFF is not needed, but I think it looks better and more
professional, but that is just me. I do realize I have rambled on for a
while here but I do hope it helps. I have been out of the python loop
for a while, but am being forced back into it, which really don't hurt
my feelings at all, just had to wait for a project that required it:)
Anyway if you dont understand anything just let me know and i'll try to
do a better job explaining it.
