[Edu-sig] What is the Best Way to use Python in the Windows Command Line

Several options, Charles.
If they typically work from a particular directory, you can have them copy
into that directory a batch file like py.cmd:
start "Python Enabled Command Window"
Double clicking on it starts a console window that has Python in the path,
and any further console window you open from within it with the start
command inherit the same path.
You can omit the idlelib part if you like.
If you want the Python directories in the path generally, without diddling
with the control panel, and if your students are already downloading a few
files of yours, you might include pathman.exe from Microsoft's freely
downloadable "Windows Resource Kit" plus another batch file for them to
double click on:
pathman /au C:\Python26;c:\python26\tools\scripts;c:\python26\scripts
This changes the global path when you open a console window in the future.
If you have both 2.6 and 3.0 installed and want to go back and forth between
having them as defaults, you can have a batch file like the following and a
similar one to do the reverse.
ftype Python.CompiledFile="C:\Python26\python.exe" "%%1" %%*
ftype Python.File="C:\Python26\python.exe" "%%1" %%*
ftype Python.NoConFile="C:\Python26\pythonw.exe" "%%1" %%*
pathman /rs C:\Python30;c:\python30\tools\scripts;c:\python30\scripts
pathman /as C:\Python26;c:\python26\tools\scripts;c:\python26\scripts
The first three lines make the right behavior when selecting a file in the
GUI Windows directory browser.
The /rs and /as in the pathman calls refer to the system path. If for some
reason you are only manipulating the user path, use /ru and /au.
