Let's have a look at the following steps:

1. To create a process, we need to import the multiprocessing module with the following command:

import multiprocessing

2. Each process is associated with the myFunc(i) function. This function outputs the numbers from 0 to i, where i is the ID associated with the process number:

def myFunc(i):
    print ('calling myFunc from process n°: %s' %i)
    for j in range (0,i):
        print('output from myFunc is :%s' %j)
    

3. Then, we define the process object with myFunc as the target function:

if __name__ == '__main__':
    for i in range(6):
        process = multiprocessing.Process(target=myFunc, args=(i,))

4. Finally, we call the start and join methods on the process created:

     process.start()
     process.join()

 Without the join method, child processes do not end and must be killed manually.
