Answer: print(f'{air_temperature:.1f}C')
Step-by-step explanation:
The letter 'f' indicates that this string is used for formatting. 1f basically means that we are looking for one decimal point. That is how we get the .4 instead of more decimals.
If we had 3f for example, we would see 36.400
We then include C after the brace so that is ends with C.
