Hi.
{0:3.1f} is a way of formatting number (in this case, the temperature value).
f for float; 3 for the total number of places to be reserved for the whole string, 1 for the decimal places.

As for the b’, it converts the value into bytes literal. This article explains it well for beginners:
I hope this helps.
