将1个变量中的2字节十六进制分成2个

Question

I have

2bytes=0x1AFF

and I want to split the variable "2Bytes" to save 0x1A in one independent variable, and 0xFF in another independent variable. Saving in one variable the first byte and in the another the second:

Byte1=0x1A
Byte=0xFF

How can I do that ? Thanks

Answer 1

I would use the bitwise and & and bit shifting >> operators:

value = 0x1AFF
values = []
while value != 0:
    values.append(value & 0xFF)
    value = value >> 8

print(values)
# [255, 26]
# ==
# [0xFF, 0x1A]

This should produce the bytes (in reverse order) of value as a list in the variable values .
