I don't like the 'leading 0 is octal'-syntax. I typically think of
numbers as decimal and bytes as hexadecimal.
I would even write something like this:
# iterate over bits 3 to 5
for i in range(0x00, 0x40, 0x08):
...
print "0x%02x\n" % i
0x00
0x08
0x10
0x18
0x20
0x28
0x30
0x38
For me it is easier to see where the bits are in the hex notation.
And it is very common to use numbers with leading zeroes
that are hexadecimal. Like this:
# print address and data
for i in range(0x10000):
print "%04x: %d\n" % i, data[i]
0000: ...
0001: ...
...
000f: ...
0010: ...
...
When you are looking for examples of numbers where leading zeroes
do not mean octal then consider decimal AND hexadecimal.

I disagree.
