cd into another directory to execute a script

I need to cd into a particular directory to run a jar package. This is what I'm currently trying to do, albeit unsucessfully:

subprocess.call(['cd','sales'])
subprocess.call(shlex.split("""java Autoingestion %s %s %s Sales Daily Details %s"""%                                                                         
            (self.username, self.password, self.vendor_number, self.date)))

How would I correctly cd into the sales folder and execute this script?

Use os.chdir() to change the current directory to a specified one.

I would suggest you to use subprocess.Popen() rather than subprocess.call(). If you wish to set the environment yourself before running the java code, like setting JAVA_PATH, etc, it is easy by setting the env argument of Popen.

from subprocess import Popen
from os import chdir
from os.path import exists

sales_dir = "/home/ubuntu/sales"

# Sanity check for the directory
if exists(sales_dir):
    chdir(sales_dir)

new_proces = Popen("java Autoingestion %s %s %s Sales Daily Details %s" % 
             (self.username, self.password, self.vendor_number, self.date))

You should do

subprocess.call(["java","Autoingestion",self.username, self.password, self.vendor_number, "Sales","Daily","Details",self.date, cwd="sales")

Notice that you should not do shlex.split as it is insecure

Use os.chdir() before your second Popen call (and get rid of the first Popen call).

One way is to use os.chdir() before creating the Java subprocess.
