Hey Mark,

Also have a look at the os.path module.  Because you want these scripts
to work on both Linux and Windows, using os.path will let you avoid
writing platform specific code to handle your slashes.

For example:
import os
path_parts_list = ['C:', 'testing_it.txt']

Now, os.path.join will join those path parts together with whatever is
appropriate for the OS you are running on:

os.path.join(path_parts_list)

This should give you:
'c:\testing_it.txt' on Windows and
'c:/testing_it.txt' on Linux (which doesn't make sense, but demonstrates
how os.path can handle your os-specific slashes for you).

There are lots of helpful path related built-ins:

Jeez! I'm retarded. It works like a charm now.

Backslash is an escape character in Python string constants. \t actually 
inserts a tab character in the string.

You have several choices:

'C:/testing_it.txt' - forward slashes work fine too
'C:\\testing_it.txt' - double the \ to make it a literal.
r'C:\testing_it.txt' - 'r' prefix makes it a 'raw' string, backslashes 
are (mostly) treated as literals rather than escapes.

Ahh, yes. Your main trouble seems to be the use of \ instead of / in
'C:\testing_it.txt'

Windows uses \, whereas python uses /. So you can replace 'c:\'
with your choice of the following:

'c:/' (replacing \ with /)
r'c:\' (the 'r' before the string tells python it's a raw string)
'c:\\' (the first \ telling python to take the second \ at face value)

Well, immediately I am having problems. Be patient with me.

This what I have...

copy_file.py


import os
import shutil as sh

sh.copy('C:\testing_it.txt', 'D:\')
raw_input("Done!")



...and it's not working. Obviously, I'm trying to copy a text file on C:\ to 
D:\.

Re: [Tutor] Convert my .bat and .vbs to .py

[Rob Andrews]

I can confirm it works nicely in Windows. I have a script I use
several times daily to create working directories on a local
workstation by copying over arbitrarily deep directory trees into an
"original files" directory under a root directory named by job number.
The local workstation on which I have python running is a Windows
machine, and it's agnostic about the operating systems of the network
drives from which the data is gathered.

Quite handy and not even a very long program after the try/except
bulletproofing is added.

Maybe there's a way to use shutil's copytree function with os module's
remove function or shutil's rmtree function? If not, use the glob module
to gather the file names and then walk the results of the glob with a
for loop and use shutil's copyfile function.

You might want to look at my Using the OS topic in my tutorial
It covers basic file manipulation and starting external programs 
etc.

> that they can be run on either my windows or linux workstations.

That might be harder than you think due to differences in paths etc.
Also some external commands will be different, and ones with the 
same name take different arguments/orders or args etc

If you write them in pure Python you should be OK but if you 
just run sequences of OS commands (typical of batch files) 
then you might run into problems.

Re: [Tutor] Convert my .bat and .vbs to .py

If you import os, os.path, and shutil (only the ones you need,
although I wind up using all three for this sort of task), you can do
all that you have in mind and more.

os.path opens up some pretty painless methods for doing things like
testing to make sure the file exists in a given location before
copying it (or deleting it), which can save a good bit of heartache.

shutil can be used for not only copying files, but even copying entire
directory trees.

Hey Mark, welcome aboard!

There are a few different approaches you could take to convert your
scripts.  If most of your scripts are related to copying/moving files,
I'd have a look at Python's shutil module.  I think it'll work in both
Windows and Linux but I don't have a Windows machine handy to test it.



Have fun,

Eric.

Welcome to Python. You probably want to look at the shutil
module, possibly combined with the os module:
