Fair enough. But try this (or any of its many equivalents) with a proportional font or tabs:

      #!/usr/bin/env python
      # -*- coding: utf-8 -*-
      
      s = ''
      
      for y in range(1,13):
        for x in range(1,13):
          s += '%4d' % (x*y)
        s += '\n'
        
      print(s)
      
         1   2   3   4   5   6   7   8   9  10  11  12
         2   4   6   8  10  12  14  16  18  20  22  24
         3   6   9  12  15  18  21  24  27  30  33  36
         4   8  12  16  20  24  28  32  36  40  44  48
         5  10  15  20  25  30  35  40  45  50  55  60
         6  12  18  24  30  36  42  48  54  60  66  72
         7  14  21  28  35  42  49  56  63  70  77  84
         8  16  24  32  40  48  56  64  72  80  88  96
         9  18  27  36  45  54  63  72  81  90  99 108
        10  20  30  40  50  60  70  80  90 100 110 120
        11  22  33  44  55  66  77  88  99 110 121 132
        12  24  36  48  60  72  84  96 108 120 132 144
      

Or this:

        #!/usr/bin/env python
        # -*- coding: utf-8 -*-
        
        from numpy import arange
        
        # dimensional parameters for the set
        
        yl = -1.2
        yh = 1.2
        ys = .05
        
        xl = -2.05
        xh = 0.55
        xs = 0.03
        
        def mandelbrot(c):
          z = 0
          for n in range(10):
            z = z*z + c
            if(abs(z) > 2):
              return '.'
          return '*'
          
        s = ''
        for y in arange(yl,yh,ys):
          for x in arange(xl,xh,xs):
            s += mandelbrot(complex(x,y))
          s += '\n'
          
        print(s)
