Firstly, you don't need "compute". Every function computes.
Secondly, fix the spelling of temperature.
Thirdly, we can make it easier to read by spreading it out.
##############################################################
def wind_chill_temperature(
T:'Temperature, dF',s:'Wind speed, mph')->'dF':
'http://www.erh.noaa.gov/er/iln/tables.htm#heat index'
if T < 40:
return 35.74 + 0.6215*T + s**0.16*(T*0.4275-35.75)
else: return T
There is no shortage of newlines. They are a renewable resource, don't be
afraid to use a couple of extra lines to make your code more readable.
