I'm currently trying to convert a digit from decimal to hex,
however I need the full 4 digit hex form. Python appears to
be shortening the form.
Example:
num = 10
num = "%x"%(num)
print(num)
a
num = 10
num = "%#x"%(num)
print(num)
0xa
I need it to output as 0x0a, and the exercise is requiring
me to use %x to format the string. Any help would be
appreciated.
Though it feels hokey to me, using
"%#04x" % 10
works for me. The "#" adds the "0x" prefix (the "alternate
form"), the "0" pads with zeros, and the "4" is really "2 places
+ 2 characters for the prefix". So if you want 4 hex characters
+ the 2 prefix characters, you'd use "%#06x". IMHO, this would
make more sense if it didn't take the 2-character prefix into
consideration (being written as "%#02x" for a byte or "%#04x" for
a short), but it's not really a burr in my saddle.
