Look at the shutil module.

Another ascpect to my question of yesterday:

The problem with
f=open(aFile)
x=f.read()
f.close
f.open(toFile)
f.write(x)
f.close
is, that some special ASCII-codes are not copied as usual
under Windows-systems, so e.g. CarriageReturn (tested with normal
Asccii-text).

Hints?

Ciao,
Holger

Yes. As someone has pointed out, the shutil module contains the
beast you're looking for.
The Index of the Library Reference manual is often pretty helpful
about things like this (not the Module Index, the general Index).
Just click on the "i" icon at the top of any page of the library
reference if you're using the HTML version. The index may be long,
but I'm told it isn't too shabby.
(If anyone thinks additional entries are needed, send a note telling
what they are and where they should link to in the manual to
python-docs@python.org; this kind of suggestion is usually well
received by the damn fool^H^H^H^H^H^H^H^H^H^H poor bloke who receives
mail at that address.)

I believe shutil.py is an obscure name for this
particular module. I only discovered it (years ago)
by accident when looking for an example of os.path.walk.

It's probably too late, but it would be great if we
could change the name to filecopy.py, retaining
shutil.py (which could import filecopy's code).

You're doing something funny, but not sure what from your pseudo
code.

open(aFile) is equivalent to open(aFile, 'r'), which is text mode
- it will translate \r\n to \n on input. open(toFile,'w') would also
open text mode, and translate \n to \r\n on ouput. Your symptoms
match reading from a file in text mode, but writing in binary mode
(eg, open(toFile, 'wb')).

Don't worry - you're in good company. Netscape gets them confused
frequently too.

Open the file in binary mode.
