For example, a is a bytes composed of 8 bytes
a=b'/x00/x01/x02/x03/x04/x05/x06/x07'
How do I extract the first four bytes of a=to form a new bytes
I tried the following method
for i in range(0,4):
c[i]=a[i]But the result c is a list not bytes
But it doesn’t work a[i] is of type int
How to make c equal to the first 4 bytes of extracted a
That is, the result is c=b'/x00/x01/x02/x03'
