Question

Im not sure about the best way to do this but I have a python script saved as a .py. The final output of this script is two files x1.txt and y1.txt.

Basically I want

Answer 1

If your computer has the resources to run these in parallel, you can use multiprocessing to do it. Otherwise use a loop to execute them sequentially.

Your question isn't quite explicit about which part you're stuck with. Do you just need advice about whether you should use a loop? If yes, my answer is above. Or do you also need help with forming the filenames? You can do that part like this:

import sys

def myscript(iteration_number):
    xfile_name = "x%d.txt" % iteration_number
    yfile_name = "y%d.txt" % iteration_number
    with open(xfile_name, "w") as xf:
        with open(yfile_name, "w") as yf:
            ... whatever your script does goes here

def main(unused_command_line_args):
    for i in xrange(1000):
        myscript(i)
    return 0

if __name__ == '__main__':
    sys.exit(main(sys.argv))

Answer 2

I'm not sure, but maybe, it can help: Suppose, I want to print 'hello' 10 times, without manually writing it 10 times. For doing this, I can define a function :

    #Function for printing hello 10 times:
    def func(x):
       x="hello"
       i=1
       while i<10 :
           print(x)
           i += 1
       else :
           print(x)

    
    print(func(1))
