I have a hex string:

mystr  = b'FFF7E7FF704268426803FF380E53131212121312000012BB01BA3300008200016D9E00016C790000865D00008206003723630D016E0271027103E8'

and want to get the int value of mystr[44:46] - it should come to 18

In python I would do

int(mystr[44:46],base=16)

but that doesn't work in MP. I've googled around but can only find python examples.

When I try

int(mystr[44:46],16)

in MP v1.16 on an ESP8266 it gives me a result of 18

Yes, that has worked for me as well. How simple and obvious these things are when you know! - Thanks
