You are looking for the chr function.
You seem to be mixing decimal representations of integers and hex representations of integers, so it's not entirely clear what you need. Based on the description you gave, I think one of these snippets shows what you want.
>>> chr(0x65) == '\x65'
True
>>> hex(65)
'0x41'
>>> chr(65) == '\x41'
True
Note that this is quite different from a string containing an integer as hex. If that is what you want, use the hex builtin.

How to convert a decimal number to hexadecimal in Python
Line 4–5: The function starts with a special case: if the input decimal_num is 0, it directly returns “0” since the hexadecimal representation of 0 is “0”. Line 8–13: Inside the while loop, the decimal number is continuously divided by 16, and the remainder is used to index into the hex_characters string to get the corresponding hexadecimal digit.

You can already use f-strings for this (unless I misunderstand what you’re after)
print(f"{0xabc:04x}")
# prints: 0abc
Note that you don’t have to convert the number to hex first for this formatting to work
print(f"{16:03X}")
# prints: 010
See the f-string documentation and the corresponding for…
