Hello,
check out the 'ABAQUS Scripting User's Manual' and 'the ABAQUS Scripting Reference Manual'. The Python Scripting Interface is quite well documented.
Here some code snipplet how to create and start a job:
----
import part
import material
import section
import job
import mesh
import assembly
import interaction
import load
# get the current modelname
CurrentModelName = session.sessionState[session.currentViewportName]['modelName']
# interact with the user for the name of the job
jobname=getInput(prompt='Job Name?:',default=CurrentModelName)
# interact with the user for some useful description of the odb
odbdescription = getInput(prompt='ODB Description?:',default='some useful description')
# now make the job
job = mdb.Job(name=jobname,model=CurrentModelName,description=odbdescription)
# start the job
job.submit()
