Hi

I'm not sure this is correct, we want to print groups of 8 bits, not 7...

Yes. Sure you want to print groups of 8 bits. However, the origin logic tries to print groups of 9 bits. 0, 1, 2, 3, 4, 5, 6, 7, 8 (%8 == 0) 0, 1, 2, 3, 4, 5, 6, 7, 8 (%8 == 0) So I think 8 should be changed to 7. Of course, I found the minor issue when the interface is used.

Ah

$ python3 -mptpython
>>> for i in range(50): 
...     if i > 0 and i % 8 == 0: 
...         print('') 
...     print(i)

The 2nd group is 7 bits rather than 8...

>>> for i in range(50): 
...     print(i) 
...     if i > 0 and i % 7 == 0: 
...         print('')
