Write a Python program that asks the user to input the current temperature in degrees Celsius and the current humidity percentage. The program should then analyze these values and print one of four possible weather descriptions: if the temperature is above 30 degrees and the humidity is above 70 percent, the program should print "Hot and humid." If the temperature is above 30 degrees but the humidity is 70 percent or below, it should print "Hot but dry." If the temperature is 30 degrees or below and the humidity is above 70 percent, it should print "Cool but humid." If both the temperature is 30 degrees or below and the humidity is 70 percent or below, the program should print "Cool and pleasant."
