Python hex()

Let’s look into some simple examples of converting integer to hexadecimal number.

print(hex(255))  # decimal
print(hex(0b111))  # binary
print(hex(0o77))  # octal
print(hex(0XFF))  # hexadecimal

Output:

0xff
0x7
0x3f
0xff

Let’s create a custom class and define __index__() function so that we can use hex() function with it.

class Data:
    id = 0

    def __index__(self):
        print('__index__ function called')
        return self.id


d = Data()
d.id = 100

print(hex(d))

Output:

__index__ function called
0x64
