for row in matrix:
for element in row:
total += element
return total

Write a Python program that uses conditional statements to provide a weather description. If the temperature is greater than 30, print "It's hot outside." If it's between 10 and 30 (inclusive), print "It's warm outside." Otherwise, print "It's cold outside."
temperature = int(input("Enter the temperature: "))
