combined files together

[Gary Wessle]

Hi

is there a module to do things like concatenate all files in a given
directory into a big file, where all the files have the same data
formate?
name address phone_no.

or do I have to open each, read from old/write-or-append to new ...

thanks

There's hardly enough code here to make a module out of this:

combined = open('...', 'wb')
for name in os.listdir(path):
infile = open(os.path.join(path,name), 'rb')
for line in infile:
combined.write(line)

It could be more efficient by reading larger chunks than single lines,
and could be more accurate by closing both input and output files when
done, but you get the point I hope.

On the other hand, if you've got the right OS, you might try something like:
os.system("cat * > combined")

I need to traverse those files in the order they were created
chronologically. listdir() does not do it, is there a way besides
build a list then list.sort(), then for element in list_of_files open
element?

thanks

are the name of the files describing the cration date, or have to rely on the
creation date ?

if the name allows to discriminate the chronology, check glob module.

yes

no

I just tried glob, it does not put out a list with file names sorted.
