How to change the hex data of a file?

Question

Python

Hey!
There is a file, in the hex editor I can change the bytes I need at a certain address. How to do it in python?
For example, my input address is "235EDF", you need to change the value from "2E" to "43".
I want to write a patch for the program. I know what to change to, but I can't figure out how. let me read something on this topic.

Answer 1

Open the file in binary mode and write your bytes there, hex is just their representation in hexadecimal form.
