How to change characters in a list to hex numbers?

key = input()

a = list(str(key))
print(a)

Does anyone know how to change that a list to get hex numbers in there? Example:

key = "abc"
>> ["a", "b", "c"]

But instead of those letters hex numbers.

Thanks.

>Solution :

Use ord to get the int representation of a character, and hex to get the hex representation of that int.

>>> [hex(ord(c)) for c in "abc"]
['0x61', '0x62', '0x63']
