usage: python [option] ... [-c cmd | -m mod | file | -] [arg] ... | |||
Options and arguments (and corresponding environment variables): | |||
-b : issue warnings about str(bytes_instance), str(bytearray_instance) | |||
and comparing bytes/bytearray with str. (-bb: issue errors) | |||
-B : don't write .pyc files on import; also PYTHONDONTWRITEBYTECODE=x | |||
-c cmd : program passed in as string (terminates option list) | |||
-d : debug output from parser; also PYTHONDEBUG=x | |||
-E : ignore PYTHON* environment variables (such as PYTHONPATH) | |||
-h : print this help message and exit (also --help) | |||
-i : inspect interactively after running script; forces a prompt even | |||
if stdin does not appear to be a terminal; also PYTHONINSPECT=x | |||
-I : isolate Python from the user's environment (implies -E and -s) | |||
-m mod : run library module as a script (terminates option list) | |||
-O : optimize generated bytecode slightly; also PYTHONOPTIMIZE=x | |||
-OO : remove doc-strings in addition to the -O optimizations | |||
-q : don't print version and copyright messages on interactive startup | |||
-s : don't add user site directory to sys.path; also PYTHONNOUSERSITE | |||
-S : don't imply 'import site' on initialization | |||
-u : force the binary I/O layers of stdout and stderr to be unbuffered; | |||
stdin is always buffered; text I/O layer will be line-buffered; | |||
also PYTHONUNBUFFERED=x | |||
-v : verbose (trace import statements); also PYTHONVERBOSE=x | |||
can be supplied multiple times to increase verbosity | |||
-V : print the Python version number and exit (also --version) | |||
when given twice, print more information about the build | |||
-W arg : warning control; arg is action:message:category:module:lineno | |||
also PYTHONWARNINGS=arg | |||
-x : skip first line of source, allowing use of non-Unix forms of #!cmd | |||
-X opt : set implementation-specific option | |||
file : program read from script file | |||
- : program read from stdin (default; interactive mode if a tty) | |||
arg ...: arguments passed to program in sys.argv[1:] | |||
Other environment variables: | |||
PYTHONSTARTUP: file executed on interactive startup (no default) | |||
PYTHONPATH : ':'-separated list of directories prefixed to the | |||
default module search path. The result is sys.path. | |||
PYTHONHOME : alternate <prefix> directory (or <prefix>:<exec_prefix>). | |||
The default module search path uses <prefix>/lib/pythonX.X. | |||
PYTHONCASEOK : ignore case in 'import' statements (Windows). | |||
PYTHONIOENCODING: Encoding[:errors] used for stdin/stdout/stderr. | |||
PYTHONFAULTHANDLER: dump the Python traceback on fatal errors. | |||
PYTHONHASHSEED: if this variable is set to 'random', a random value is used | |||
to seed the hashes of str, bytes and datetime objects. It can also be | |||
set to an integer in the range [0,4294967295] to get hash values with a | |||
predictable seed. | |||
PYTHONMALLOC: set the Python memory allocators and/or install debug hooks | |||
on Python memory allocators. Use PYTHONMALLOC=debug to install debug | |||
hooks. | |||

Here is an example of a shell script, sub.sh, to run on the batch queue:
#!/bin/bash
#SBATCH --job-name=j_Python
#SBATCH --partition=batch
#SBATCH --mail-type=ALL
#SBATCH --mail-user=username@uga.edu
#SBATCH --ntasks=1

python [options]
In the real submission script, at least all the above underlined values need to be reviewed or to be replaced by the proper values.
Please refer to Running_Jobs_on_the_teaching_cluster, Run X window Jobs and Run interactive Jobs for more details of running jobs at Teaching cluster.
Here is an example of job submission command:
sbatch ./sub.sh
