Python hexadecimal comparison

You could first of all convert your string to an integer:

s = "0x01010000"
i = int(s, 16) #i = 269484032

then, you could set up a list for the fruits:

fruits = [(0x01000000, "apple"), (0x00010000, "orange"), (0x00000100, "banana")]

for determing what fruits you have that is enough:

s = "0x01010000"
i = int(s, 16)
for fid,fname in fruits:
    if i&fid>0:
        print "The fruit '%s' is contained in '%s'" % (fname, s)

The output here is:

The fruit 'apple' is contained in '0x01010000'
The fruit 'orange' is contained in '0x01010000'

Convert your string to an integer, by using the int() built-in function and specifying a base:

>>> int('0x01010000',16)
16842752

Now, you have a standard integer representing a bitset. use &, | and any other bitwise operator to test individual bits.

>>> value  = int('0x01010000',16)
>>> apple  = 0x01000000
>>> orange = 0x00010000
>>> banana = 0x00000100
>>> bool(value & apple) # tests if apple is part of the value
True
>>> value |= banana     # adds the banana flag to the value
>>> value &= ~orange    # removes the orange flag from the value

Now, if you need to convert back to your string:

>>> hex(value)
'0x1000100'
