Create multiple files with same programm but different results

so Im having a problem with my code:

for i in range(10):
    a = ([random.randint(1, 1000) for j in range(10)])
    print(*a, sep = ".jpg, ", end = ".jpg, \n")
    f = open("test.cvs", "x")
    f.close()
        

my current output looks like this:

689.jpg, 715.jpg, 772.jpg, 639.jpg, 903.jpg, 264.jpg, 226.jpg, 629.jpg, 306.jpg, 
758.jpg, 
458.jpg, 355.jpg, 262.jpg, 889.jpg, 244.jpg, 849.jpg, 613.jpg, 439.jpg, 646.jpg,

which is perfect, i want it exactly like that, but i want to create a file for every output. It cant be the same result in multiple files. Is it possible to let the numbers generate then put the output inside a file and then again let the numbers generate again and put it in a new file. The goal is to create .cvs files Thank you in advance.
