writing code that searches for a sync pattern

Question

I have a large specific binary file of data that I need to scan for a packet sync pattern 0xEB25. how do I search the file for that specified pattern in python?

It depends on what type of file your trying to scan. If your trying to scan a text file try going to this link: https://www.geeksforgeeks.org/reading-writing-text-files-python/. It would be easier if you also provided some code. — Maxim, Jul 29 '20 at 01:33

If it's contained in a text file and that is Hex code, then this should work:

def isInFile(string):
    with open('example.txt') as f:
    if string in f.read():
        print("true")

then just run

isInFile("1110101100100101")

Where 1110101100100101 is the hex you gave converted into binary
