PATH variable in Python

How can I change the Environmental PATH variable through code in python ? I am trying to return the path of an executable file. The code does not work because the shell is pointing to another directory. Any help is appreciated.

You can use os.environ.

Example:

path = os.environ["PATH"] # a ':'-separated string
path += ":/var/custom/bin"
os.environ["PATH"] = path

Or in a single line:

os.environ["PATH"] = ':'.join(os.environ["PATH"].split(":") + ["/var/bin"])

os.environ["PATH"] += ":/usr/local/bin"

See http://docs.python.org/library/os.html#os.environ.

You aren't looking for the PATH variable. You want to either set the current working directory with os.chdir or pass the absolute path with os.path.abspath.
