Hey,
I'm working on a project for which I would like to dump data into a
file in a specified directory (that doesn't necessarily exist yet). I
know matplotlib.mlab.save(fname, X) will only work if I want to save
data from an array/list to a file in the current working directory. Is
there an easy way using matplotlib to:
A) Save a file to a specified directory rather than the current
working directory
B) Create a directory I tell it to save to if it doesn;t already exist
Thanks in advance.
Josh

Just specify the full path to the output dir:
save('/path/to/my/data.dat')
or use the os modules built-in functions for cross-platform path handling:
save(os.path.join(outdir, filename))
B) Create a directory I tell it to save to if it doesn;t already exist
You can use os.mkdir. mpl svn has a function cbook.mkdirs to
recursively make a directory path.

Ah, silly me. I forgot to notice I was using a path variable in the
string I was giving to mlab.save. Part A works just fine when I
account for that. Now that just leaves creating the directory. I like
the cbook.mkdirs implementation a lot better than the non-recursive
version in os... thanks for the tip!

Wow, that one went right by me -- somehow missed its existence.
Thanks for the pointer...

why not os.makedirs() ?
cbook.mkdirs includes a few if-then calls that only make the directory
if it doesn't already exist (in fact it actually calls os.makedirs in
the function), whereas os.makedirs raises an OSError if the folder I
specified already exists. For my purposes, the cbook implementation is
more convenient.

But given the vagueness of what I asked, you're right, os.makedirs was
a good suggestion too. Thanks. I think I need to sit down and spend
some quality time with the os module over Thanksgiving holiday...
