IntroductionIn Winnipeg, the wind can make the temperature even colder than it is without windchill. Write a program that uses input to read in an air temperature and a wind speed. Then, use the formula below to calculate and output the windchill.
|
|---|
Step 1: Get inputs/outputs needed to solve the problem
You will need the following variables in order to solve this problem.
- location - The location at which you want to calculate the windchill.
- temperatue - The temperature of your desired location
- windSpeed - The windSpeed at your desired location
- input - Used to prompt the user for input
- raw_input - Used to prompt the user for input
- windChill - The calculated wind chill of your desired location
Step 2: Write the program
#######################################################################
#This program is used to calculate the wind chill of a desired location
#input
location = raw_input("What is the location?")
temperature = input("What is the current temperature in Celsius?")
windSpeed = input("What is the wind speed in kms per hour?")
#calculate windchill
windchill = 13.12 + .6215*temperature- 11.37 * (windSpeed**0.16) + 0.3965 * temperature * (windSpeed ** 0.16)
#output
print "\n\nLocation: " + location
print "Current Temperature: %f" % temperature + " Celsius"
print "Wind Speed:%02f " % windSpeed + " km/h"
print "Temperature with Windchill: %02f" % windchill
print "Programmed by A. Student"
print "**End of Program**"
Step 3: Display the output of the program
Location: Winnipeg Current Temperature: -10.0 Celsius Wind Speed: 30.0 km/h Temperature with Windchill: -19.52049803338773 Programmed by A. Student **End of Program**
Step 4: Contrast with windChill program in Program a Day example
This Python program produces the same output as the Java WindChill program in Program-A-Day, but there are some differences which are described below.
- Python uses x**y as its Math power operator whereas Java uses Math.pow(x,y)
- Python does not perform conversion to other types but Java uses for instance double x = Double.parseDouble(y) to convert y to double data type
- In the print statements, Python specifies the format(%f = float data type) of some variable.
