Second last example on page 152

On Page 152 of 5th edition of the book, it is written that:

> Finally, you can also convert integers to base-specific strings with string formatting method calls and expression, **which return just digits, not Python literal string:**

>>> '%o, %x, %x, %X' % (64, 64, 255, 255)
'100, 40, ff, FF'

Note the problematic part above which says "which return just digits, not Python literal string". This is clearly a mistake as we can see the result is a string not a digit. Moreover, this also contradicts with what is given on page 156

> string formatting produces a string, not a number:

So as we can see, now on page 156, it says that the result is a string not a number. So there seems to be contradiction between the two quoted references(on page 152 and page 156)
