parallel computing in python script

I am using a Monte Carlo simulation. Due to this simulation, it is taking a lot of time (approximately 40 hours). Can I use parallel computing in my script? If yes, then how?

Why don't you use directly the Monte Carlo functionality within FePEST application? You can parallelize with a couple of clicks only.. Cheers Carlos

Thank you for your reply. But in my script: #There are 100 Monte carlo simulation #In each iteration of the Monte Carlo simulation, there are rainfall events lasting up to 24 hours with a step of 0.25   hours. #For each rainfall event, the stage time series is generated, which is added to the FEFLOW model for simulation and   analysis. #After each simulation, the maximum saturation at the observation node is to be extracted. Please help me with this, I will be thankful to you
