how to split this string of HEX bytes

i have the following string of hex bytes from a smart meter:

'~\xa0\x1e\x03\x00\x02\xfe\xff4\xca\xec\xe6\xe7\x00\xc4\x01A\x00\x02\x04\x12\x00\x05\x11\x01\x11\x01\x11\x00\xc7\x11 ~'

I want to separate them in a list and then pass them to decimals or int. The .split() python function won't work, any ideas?

thanks!

You can convert a string to a list of ascii values with ord.

values = [ord(c) for c in data]

Although, depending on what you want to do, you might not even need to cast your data as a list since a str is already iterable.

Instead, iterate over your characters and recover their value. Here is a simplified example.

dt = '\xa0\x1e\x03\x00\x02\xfe'

for x in map(ord, dt):
    print(x)

Output

160
30
3
0
2
254
