THIS SHOULD BE EASY! But i've been unable to find the answer to this question.
Using python, I want to read a binary file into memory, modify the first four bytes of the file, and then write the file back.
There has to be a simple way to edit four measly bytes! right?

Step 1: Searching for the word in the binary file. Step 2: While searching in the file, the variable “pos” stores the position of file pointer record then traverse(continue) reading of the record. Step 3: If the word to be searched exists then place the write pointer (to ending of the previous record) i.e. at pos.
To open the Binary Editor on an existing file, go to menu File > Open > File, select the file you want to edit, then select the drop arrow next to the Open button, and choose Open With > Binary Editor.
Write Bytes to File in Python Example 1: Open a file in binary write mode and then specify the contents to write in the form of bytes. Next, use the write function to write the byte contents to a binary file.
with open(filename, 'r+b') as f:
bytes = f.read(4)
newbytes = 'demo'
f.seek(0)
f.write(newbytes)
