I'm trying to make a program that will take a file, say my_test_file.log and make a new file called my_test_file.mdn. I'd like to be able to use this program by typing python renameprogram.py my_test_file.log into the command line. The original file will always end in .log.

In addition to the above link, take a look at docs.python.org/2/library/sys.html#sys.argv and docs.python.org/2/library/os.html#os.renameAMacK– AMacK2015-04-29 02:41:42 +00:00Commented Apr 29, 2015 at 2:41

from shutil import copyfile
from glob import glob
map(lambda x:copyfile(x,x[:-3]+"mdn"),glob("*.log"))
or perhaps more simply
...
import sys
copyfile(sys.argv[1],sys.argv[1][:-3]+"mdn")

You certainly can create a Python program that will accomplish this, but there are shell level commands that already do this.
For Linux/Unix:
mv my_test_file.log my_test_file.mdn
For Windows (see this link):
rename my_test_file.log my_test_file.mdn

I believe you could even do
mv *.log *.mdn (+1)

If you want to rename all files in the current directory, yes.

I know I can do this with unix, but the reason I'd like to do it in python is because I need to get a bunch of other data from the original file and put it into the new file in a different format I'd like to do this all with one program if possible, but that might be beyond my skills at the moment haha. This is just the first step.

@JoranBeasley: No, that wouldn't be the correct syntax. The
*.mdn wouldn't expand to what you want it to expand to, and mv would complain about the target not being a directory.
