New submission from steven Michalske <smichal...@gmail.com>:
It is a common practice to separate hex digits with a "thousands" separator
every 4 hex digits.
0x1234_abcd
Although python does not accept the _ as a thousands separator in hex notation,
neither is the thousands separator in base 10
Snippet that prints hex thousands with a _ separator
number = 0xef5678abcd1234
def hex_thousands(number):
txt="{0:X}".format(number)
txt_out = ""
i = range(-4,-1 * (len(txt) + 4), -4)
ii = i[:]
ii.insert(0, None)
for (j, k) in zip(i, ii):
if txt_out:
txt_out = "_" + txt_out
txt_out = txt[j:k] + txt_out
return txt_out
print hex_thousands(number)
