I have a script that uses argsparse to modify its inputs. For the example below, it runs a series of simulations, one after the other, based on the given arguments: def main(): parser = argparse.ArgumentParser(description="Simulation of drivers' behavior") parser.add_argument('-f', '--fleet', help='Fleet sizes to simulate, formatted as comma-separated list (i.e. "-f 250,275,300")') parser.add_argument('-m', '--multiplier', help='Surge multiplier, formatted as comma-separated list (i.e. "-m 1,1.5,2")') args = parser.parse_args() if args.fleet: fleet_sizes = [int(x) for x in args.fleet.split(',')] else: fleet_sizes = FLEET_SIZE if args.multiplier: surges = [float(x) for x in args.multiplier.split(',')] else: surges = [SURGE_MULTIPLIER] and from command line I typically run it as: python script.py -f 1000,1500 -m 1,2 Now, I want to use my linux bash to run this scripts in parallel. The typical approach seems to be something like this: for i in {1000, 1500}; do python script.py -f i & done; done But this doesn't work, because it can't parse i properly: ValueError: could not convert string to float: 'i' (I have tried changing my argparse handling function, but that didn't seem to solve it). Some solutions suggest using sys.argv[1] but 1) I don't want to change from argparse to that 2) it seems like argparse is the superior way in general. My question is this: How can I use bash to run my python script in parallel, given that it uses argparse to collect input for each variable in the code? Continue reading...
