my_address = re.search(rb'\x80\xC9.{4}\x94\x12\x8A\x41\x08', bytes).start() + 5
Read the doc but I'm a bit confused.
My guess is
\x80\xC9\BYTE\BYTE\BYTE\BYTE\BYTE\x94\x12\x8A\x41\x08\BYTE\BYTE\BYTE\BYTE\BYTE\my_address\
Thanks

How can I return operators in python? I tried this but it didn't work obviously:
def plus():
return +
Is it even possible to write code like this without using the plus operator?
print(3plus()4)
Like this
import operator
print(operator.add(3,4))

I cam across this function '#' in numpy. But I am not able to figure out what it is doing or able to get documentation for it. Could someone please point me to the documentation or tell what it is doing? Code is below
import numpy as np
w = np.array([[1,2,3,4],[2,3,1,3]])
x1 = np.array([0,1,0,1])
s = w#x1
