How do I convert a hexstring to hex?

Question

If I have a string with the following value:

STR = "00DE" 

how do I convert that so that STR becomes 0x00DE ? What function do I use?

Answer 1

If you mean you want STR to be a string in the form you describe, the simplest way is to prepend '0x' to the string:

STR = '0x' + STR

If you mean that you want STR to become an integer with the indicated numeric value, then invoke the int() constructor:

STR = int(STR, 16)
