The hex() function converts a specified integer number into a hexadecimal string representation.
Use int(x, base) with 16 as base to convert the string x to an integer. Call hex(number) with the integer as number to convert it to hexadecimal.
hex_string = "0xAA"
"0x" also required
an_integer = int(hex_string, 16)
hex_value = hex(an_integer)
print(hex_value)
Output

r/learnpython on Reddit: String to HEX
September 2, 2024 -
I am wanting to take a normal string, "My water bottle is blue" for example, and converting that into the HEX representation of how it would be stored in a txt file. I've tried .encode, binascii.hexlify, and a few other things. Any help would be appreciated.

I've tried .encode, binascii.hexlify, and a few other things. Ok, well, encode was the correct one, so do that.

To be clear: do you want the actual bytes that would be in the file? Then .encode. Do you want a string of hex representing those bytes to make it easier for a human looking at the string to know the byte values? Then encode then hexlify.

Problem parsing hex formatted as \x48\x45\x4c\x4c\x4f
A "\x48" is literally the same as "H". You don't have to do any conversion because it's already the same thing. It's just a different way of writing it. >>> "\x48" == "H" True More on reddit.com

March 25, 2019Need some help with converting hex to bytearray for long strings
then the byte array should look like this ['0xaa','0xbb','0xcc','0xdd','0xee','0xff','0x00','0x11','0x22','0x33', '0x44', '0x55','0x66','0x77','0x88','0x99'] Note that this is different to the examples you give down below - this is a list of strings, each representing a hex value. Whereas the bytearray examples in the config are arrays of bytes (provided as a list of integers written as hex literals). I assume you mean the latter, since that makes more sense for something called a byte array (especially if using python's bytearray type). For this, you can fairly easily convert the hex into a bytearray object by using the bytearray.fromhex method. Eg: >>> b = bytearray.fromhex("aabbccddeeff00112233445566778899") >>> b bytearray(b'\xaa\xbb\xcc\xdd\xee\xff\x00\x11"3DUfw\x88\x99') If you do want your list of strings, you could convert back fairly easily with: >>> [hex(byte) for byte in b] ['0xaa', '0xbb', '0xcc', '0xdd', '0xee', '0xff', '0x0', '0x11', '0x22', '0x33', '0x44', '0x55', '0x66', '0x77', '0x88', '0x99'] Though if you don't need the bytearray version, you could also construct it by string slicing the original hex string without the round-trip, though this way is probably still easier.

How To Convert String To Hex In Python?

Line 10: We also print the value type to confirm that the string is now in the form of an integer. Line 12: We know the in-built hex(n) method accepts the integer value, converting the integer to the hexadecimal string. That’s why we need to convert the string to an integer to pass it into the hex () method.

Try this:
hex_str = "0xAD4"
hex_int = int(hex_str, 16)
new_int = hex_int + 0x200
print hex(new_int)
If you don't like the 0x in the beginning, replace the last line with
print hex(new_int)[2:]

Use int function with second parameter 16, to convert a hex string to an integer. Finally, use hex function to convert it back to a hexadecimal number.
print hex(int("0xAD4", 16) + int("0x200", 16)) # 0xcd4
Instead you could directly do
print hex(int("0xAD4", 16) + 0x200) # 0xcd4
