It is necessary to make a cycle that will constantly add to the unit and print numbers to the console in the following form: 000 001 002 003 ... 011 012 013 ... 101 102, etc.

    Thus displays the numbers from 000 to 999 inclusive from the new line:

    for i in range(1000): print(str(i).zfill(3))

    Or a space:

     for i in range(1000): print(str(i).zfill(3), end=' ')

    The str.zfill (3) function complements the str string up to 3 characters, filling the left with zeros.

      It can be much easier:

       for i in range(1000) print('{:03d}'.format(i)) # print('%03d' % i)

        To print numbers on the same line with a pause:

         import time for i in range(1000): print('\r%03d' % i, end='', flush=True) time.sleep(1)
